Answer:

Janice required 30 tablespoons of butter, 380 Jet-Puffed Marshmallows and 60 cup of Kellogg's rice krispies cereal to yield 120 servings.

Step-by-step explanation:

Given that 3 tablespoons of butter, 38 Jet-Puffed Marshmallows, and 6 cup of Kellogg's rice krispies cereal) yields 12 servings.

Now, Janice has to make for 30 people and each with 4 servings for the Christmas Party.

So, there are total (30 × 4) = 120 servings required to make.

So, each and every ingredients of the dish will be required to be made 10 times.

Therefore, Janice required 30 tablespoons of butter, 380 Jet-Puffed Marshmallows and 60 cup of Kellogg's rice krispies cereal to yield 120 servings. (Answer)  

Janice will need 30 tablespoons of butter, 380 marshmallows, and 60 cups of rice krispies cereal for the Christmas Party.

To find out how many of each ingredient Janice will need, we need to calculate the total servings required for the Christmas Party. She is expecting 30 people and wants everyone to have 4 servings each. So the total servings required would be 30 * 4 = 120 servings.

Now, we can calculate the ratio of servings to each ingredient. If 12 servings require 3 tablespoons of butter, then 120 servings would require (120/12) * 3 = 30 tablespoons of butter.

Similarly, if 12 servings require 38 marshmallows, then 120 servings would require (120/12) * 38 = 380 marshmallows. And if 12 servings require 6 cups of rice krispies cereal, then 120 servings would require (120/12) * 6 = 60 cups of rice krispies cereal.

So, Janice will need 30 tablespoons of butter, 380 marshmallows, and 60 cups of rice krispies cereal for the Christmas Party.

Answer:

92.11 cm³

Step-by-step explanation:

The figure below;

We are required to determine the volume of the figure;

The volume of a hemisphere is given by;

Volume hemisphere = 2/3πr³

Taking π to be 3.14

The Volume  of the two hemisphere;

             = 2/3 × 3.14 × 2³

             = 16.75 cm³

Volume of the cylinder;

Volume = πr²h

             = 3.14 × 2² × 6

             = 75.36 cm³

Thus, volume of the figure;

Answer:

[tex]y = 2x - 1[/tex]

Step-by-step explanation:

The line shown is a straight line its equation is of the form.

[tex]y = mx + c[/tex]

Where m is the slope and c is the y-intercept.

From the graph, the slope is

[tex]m = \frac{rise}{run} [/tex]

[tex]m = \frac{2}{1} = 2[/tex]

The y-intercept from the graph is where the line intersects the y-axis, so c=-1

We substitute the values to get:

[tex]y = 2x - 1[/tex]

Explanation of how to find the equation of lines based on their slopes and intercepts.

Equation of the line: The equation of the left line is y = -x + 1 and the equation of the right line is y = 1/2x - 1/2.

Using Slope-Intercept Form: The slope-intercept form of the equation y = mx + b helps determine the equations of lines based on their slopes and intercepts.

Point-Slope Formula: By using the point-slope formula, which utilizes a point on the line and the line's slope, we can find the equation of a line.

Answer:

Step-by-step explanation:

function 1 : y = 4x + 5

In y = mx + b form, which is what ur equation is in, the slope can be found in the m position. So the slope of this function is 4.

function 2 : (1,6),(3,10)

slope = (y2 - y1) / (x2 - x1)

(1,6)...x1 = 1 and y1 = 6

(3,10)...x2 = 3 and y2 = 10

now we sub

slope = (10 - 6) / (3 - 1) = 4/2 = 2

B. Function 1, because the slope is 4 and the slope of function 2 is 2. <==

There are three terms in polynomial

Solution:

Given polynomial is:

[tex]5x^2+3x-4[/tex]

We have to find the number of terms in polynomial

A term can be a signed number, a variable, or a constant multiplied by a variable or variables

When a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.

Therefore, terms in polynomial are:

[tex]5x^2+3x-4\\\\Terms: 5x^2 \text{ and 3x and -4 }[/tex]

Thus there are three terms in polynomial

Answer:

[tex] P(27.8 < X <30.5)=P(X>27.8)-P(X>30.5)=0.025-0.0015=0.0235[/tex]

Step-by-step explanation:

The empirical rule, also known as three-sigma rule or 68-95-99.7 rule, "is a statistical rule which states that for a normal distribution, almost all data falls within three standard deviations (denoted by σ) of the mean (denoted by µ)".

Let X the random variable who represent the lifespans of tigers in a particular zoo.

From the problem we have the mean and the standard deviation for the random variable X. [tex]\mu=120 , \sigma=110[/tex]

On this case in order to check if the random variable X follows a normal distribution we can use the empirical rule that states the following:

• The probability of obtain values within one deviation from the mean is 0.68

• The probability of obtain values within two deviation's from the mean is 0.95

• The probability of obtain values within three deviation's from the mean is 0.997

We want to find this probability:

[tex] P(27.8 < X <30.5)[/tex]

And in order to calculate how many deviation we are above/below the mean we can use the z score given by:

[tex]z =\frac{x-\mu}{\sigma}[/tex]

And if we use this formula for the two values given we have:

[tex] z_1 = \frac{27.8-22.4}{2.7}=2[/tex]

[tex] z_1 = \frac{30.5-22.4}{2.7}=3[/tex]

So we have values between 2 and 3 deviations above the mean.

We can use the following probabilities

[tex]P(X<\mu -\sigma)=P(X <19.7)=0.16[/tex]    

[tex]P(X>\mu +\sigma)=P(X >25.1)=0.16[/tex]  

[tex]P(X<\mu -2*\sigma)=P(X<17)=0.025[/tex]    

[tex]P(X>\mu +2*\sigma)=P(X>27.8)=0.025[/tex]

[tex]P(X<\mu -3*\sigma)=P(X<14.3)=0.0015[/tex]

[tex]P(X>\mu +3*\sigma)=P(X>30.5)=0.0015[/tex]

And we can find this probability on this way:

[tex] P(27.8 < X <30.5)=P(X>27.8)-P(X>30.5)=0.025-0.0015=0.0235[/tex]

To estimate the probability of a tiger's lifespan falling between 27.8 and 30.5 years, we can use the empirical rule, which states that approximately 95% of the data falls within two standard deviations of the mean.

To estimate the probability of a tiger living between 27.8 and 30.5 years, we can use the empirical rule. According to the empirical rule, approximately 68% of the data falls within one standard deviation of the mean, and approximately 95% falls within two standard deviations. Since the mean is 22.4 years and the standard deviation is 2.7 years, we need to find the probability that a tiger's lifespan falls between 27.8 - 22.4 = 5.4 years and 30.5 - 22.4 = 8.1 years.

Since 5.4 years and 8.1 years are less than two and three standard deviations away from the mean, respectively, the probability can be estimated to be approximately 95% using the empirical rule.

You should multiply [tex]\frac{9}{5}[/tex] with [tex]\frac{-5}{9}[/tex] to get a product of -1

Solution:

Let the number to be multiplied be "a"

Given that,

By what number would you multiply 9/5 to get a product of -1

'a" multiplied with 9/5 should give a product -1

Therefore, writing it mathematically we get,

[tex]a \times \frac{9}{5} = -1[/tex]

Solve the above equation for "a"

[tex]a \times \frac{9}{5} = -1\\\\a = -1 \times \frac{5}{9}\\\\a = \frac{-5}{9}[/tex]

Therefore, you should multiply [tex]\frac{9}{5}[/tex] with [tex]\frac{-5}{9}[/tex] to get a product of -1

Final answer:

To multiply 9/5 by a number to get -1, you must multiply it by -5/9. This is found by setting up an equation to solve for the unknown number and then isolating the variable on one side of the equation.

Explanation:

To find by what number you would multiply 9/5 to get a product of -1, we can set up an equation that represents this situation:

Let x be the number we are looking for. Then we have the equation: (9/5) × x = -1

To solve for x, we need to divide both sides of the equation by (9/5): x = -1 ÷ (9/5)

Multiplying by the reciprocal of (9/5), which is (5/9), we get:

x = -1 × (5/9)

x = -5/9

Therefore, you must multiply 9/5 by -5/9 to get a product of -1.

step-by-step explanation:

Answer:

Since the two angles are across from each other that tells us that they are equal in length, so we want to set them equal to each other

3x+50=6x-10, Now we want to solve it like a normal equation, get x by itself

First add 10 to each side

3x+50+10=6x-10+10

3x+60=6x

Now we want to subtract 3x from each side

3x-3x+60=6x-3x

60=3x

Now divide both sides by 3

60/3=3x/3

In dividing fractions, you do the inverse. (Also called the reciprocal.)

So take that attachment you attached as a example.

----    ÷   ----  =     ------     ÷    ------

32          5           32               3

Another reminder, when you find the reciprocal, you now multiply instead of divide. (Do not question the math world. I questioned it, and I paid the price. TnT)

So 21/32 multiplied by 5/3 would be....

21              5             105

p² + (p²+14p+49) = 169

2p² + 14p + 49 - 169 = 0

2p² + 14p - 120 = 0

2p² + 24p - 10p - 120 = 0

2p(p+12) - 10(p+12) = 0

(p+12)(2p-10) = 0

p+12 = 0 , or 2p-10 = 0

p = -12 or 5

p^2 + p^2 + 7^2 = 13^2

Square Root the both side of the equation.

√{p^2} + √{p^2} + √{7^2} = √{13^2}

p + p +7 = 13

2p + 7 = 13

collect like term of the numbers

2p = 13 - 7

2p = 6

Divide both side by the coefficient of p.

2p/2 = 6/2

Step-by-step explanation:

The absolute change is the difference between the earnings numbers:

  $15,556,113 -8,556,965 = $6,999,148

__

The relative change is the ratio of this difference to the original amount:

  $6,999,148/$8,556,965 × 100% ≈ 81.794748% ≈ 81.79%

The absolute change in opening weekend earnings from the original Footloose to its remake is $6,999,148, and the relative change is approximately 81.74%.

To calculate the absolute change in opening weekend earnings from the original Footloose movie to its 2011 remake, we subtract the earnings of the original movie from the earnings of the remake. Thus, the absolute change is $15,556,113 - $8,556,965 = $6,999,148.

To find the relative change, we divide the absolute change by the original amount and then multiply by 100 to get a percentage. This gives us ($6,999,148 / $8,556,965) * 100 ≈ 81.74%. Hence, the relative change is approximately 81.74%.

The absolute change represents the direct increase in dollar amount, while the relative change gives us the percentage increase from the original to the remake's opening weekend earnings, providing insight into the growth rate.
