Your problem directly states to divide the amount in money by the amount of children

Answer:

d. 165 calories

Step-by-step explanation:

First of all, we would find the amount of calories in 1 gram of the artificial sweetener

1 gram = 220/75

1 gram = 2.93 calories

Therefore, 484 grams has;

484 * 2.93 = 165.2

Approximately, this is equal to 165 calories.

Method 2

220 grams of the artificial sweetener has 75 calories.

484 grams of the artificial sweetener has x calories.

Translating the word problem into an algebraic equation, we have;

220 = 75

484 = x

Cross-multiplying, we have;

220x = 75*484

220x = 36300

x = 36300/220

x = 165 calories.

What is graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

This graph represents the function h(x)=2sin(x+π/2)-1.

The range is the set of values that correspond with the domain.

Domain of graph: (−∞,∞),{x|x∈R}

Range of graph: [−3,1],{y|−3≤y≤1}

The percentage illumination of the moon's surface is not a linear function of day

From the complete question, the dataset can be represented using the following table:

Days   Percentage Illumination

1           2%

2          6%

3          50%

4          100%

Notice that as the number of days increase by 1, the percentage illumination of the moon increase at different intervals

This means that the percentage illumination is not a linear function of day

Answer:

a. The 95% confidence interval is 0.799<p<0.847

b. The sample size n is 622

Step-by-step explanation:

A

P^ = 823/1000

= 0.823

At 95% confidence interval

P^ +- z-alpha/2√p^(1-p^)/n

z-alpha/2 = 1.96

When we insert values we get:

0.823+-1.96√0.823(1-0.823)/1000

= 0.823+-1.96√0.000145671

= 0.823+-1.96(0.012069)

= (0.8467, 0.7993)

The 95% confidence interval is 0.799<p<0.847

Answer:

.79/4= .197. Or 20 cents each

The cost per unit of lemon in Option A is same as given per unit cost of lemon in grocery store that is $0.1975

Cost of per unit  is cost of one unit. Cost per unit can be calculated simply by dividing the total cost of all items by the quantity of given item.

Given Cost of 4 lemons  in a grocery store = $ 0.79

Cost of 1 lemon in the grocery store = total cost / 4  = $ 0.79÷ 4 = $0.1975

To check pricing option for same pricing check per unit price of each option.

A.  Given twelve lemons for $2.37

    Given Cost of 12 lemons = $ 2.37

    Cost of 1 lemon = total cost / 12  = $ 2.37 ÷ 12  = $0.1975

B. Given three lemons for $0.65

    Given Cost of 3 lemons = $ 0.65

    Cost of 1 lemon = total cost / 3  = $ 0.65 ÷ 3 = $0.2167

C. Given six lemons for $1.20

    Given Cost of 6 lemons = $1.20

  Cost of 1 lemon = total cost / 6  = $ 1.20 ÷ 6 = $0.2

D. Given  two lemons for $0.35

    Given Cost of 2 lemons = $0.35

  Cost of 1 lemon = total cost / 2  = $ 0.35 ÷ 2 = $0.175

Therefore , option A has same per unit cost $0.1975  as given pricing of the grocery store.

Answer:

a. 99

b. 12.31

Step-by-step explanation:

a. Estimate of the population mean number of units sold per month

n = Number of Data Values = 5

Sum of Data Values = Σxi =97 + 120 + 88 + 97 + 93 =  495

Sample Mean = X = Σxi/n = 495 / 5 = 99

The population mean number of units sold per month is 99

b. Estimate of the population standard deviation

Month    Data (x)     X    x - X    (x - X)^2

   1             97          99     -2         4

   2            120        99      21       441

   3             88         99      -11       121

   4             97         99      -2        4

   5             93         99      6         36

Sum of deviation squared          606

s^2 = Sample Variance = Σ(xi - X)2/(n - 1)

Sample Variance = 606/4 = 151.5

Sample Standard Deviation = √Sample Variance

Sample Standard Deviation = √151.5

Sample Standard Deviation = 12.30853362509117

Sample Standard Deviation = 12.31

The point estimate of the population standard deviation is 12.31

Answer:

y - 8 = 1/3 (x + 2)

Step-by-step explanation:

The equation y - 8 = 1/3 ( x + 2) has a slope form for the line that has a slope 1/3 and passes through (-2,8). The answer to the question is y - 8 = 1/3 (x + 2).

Hope this helps!

The equation of the line will be written as to y - 8 = 1/3 (x + 2).

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the line has a slope 1/3 and passes through (-2,8). The equation of the line will be,

y - y₁ = m(x - x₁)

y - 8) = (1/3)(x + 2 )

Therefore, the ​equation of the line is equal to y - 8 = 1/3 (x + 2).

Answer:

45

Step-by-step explanation:

[tex]x[/tex] - [tex]y[/tex] = 30 and [tex]y[/tex] = 15

So, I guess you are just messed up with the Xs and Ys.

And I'm not sure what is the 4. ООО  8  80  200 about but here is my guess :

So [tex]x[/tex] - [tex]y[/tex] = 30 and [tex]y[/tex] = 15.

First step, substitute the [tex]y[/tex] into the equation [tex]x[/tex] - .

So, it would be

[tex]x[/tex] - 15 = 30.

Now, we need the value of [tex]x[/tex].

[tex]x[/tex] - 15 = 30

Group the terms together :

[tex]x[/tex] - 15 ( +15 ) = 30 ( +15 )

So, [tex]x[/tex] would be equals to 30 + 15. And in other words, it would be 45.

So :

[tex]x[/tex] = 45.

Wanna check whether my answer's correct?

Substitute [tex]x[/tex] into [tex]x[/tex] - 15 = 30

That would be :

45 - 15 = 30

So is 45 - 15 = 30?

Yep.

So 45 is the answer.

The value of X is 45.

Step-by-step explanation:

If we call Jackie's apples a, then Mark has a - 4 apples. Therefore, together they have a + (a - 4) apples, and we know that they have a total of 12 apples so we can write a + (a - 4) = 12 to represent the situation. On the other hand, if Mark has a apples, then Jackie has a + 4 apples, so we can also write a + (a + 4) = 12 to represent the situation as well. Therefore, both of the equations would work.
