9 muffins and 15 pizza pies
Answer: 9 muffins sold. 15 pizza pies sold.

Explanation: a bakery sells 3 muffins for every 5 pizza pies.

If muffins=

Pizza pies=5x

The bakery sold a total of 24 muffins and pizza pies together.

3x + 5x = 24

8x = 24

Dividing both sides by 8, we get..

X=3

Muffins = 3 x 3 = 9

Pizza pies = 5 x 3 = 15.

Find 4cos2a, if
[tex] \cos(a) = \frac{ \sqrt{3} }{2} [/tex]

Answers

If you mean to find 4 cos(2a), then recall the double angle identity for cosine:

cos(2x) = 2 cos²(x) - 1

so that

4 cos(2a) = 4 (2 cos²(x) - 1) = 4 (√3 - 1)

If the data analyst hypothesizes that grocery sales are lower on Sunday than on other days, the null hypothesis would likely state that:

Answers

Answer:

The answer is "Grocery sales are lower or no different on Sunday than on other days"

Step-by-step explanation:

Its null hypothesis does not always consider any discrepancy between both the comparable qualities throughout facts and figures. Furthermore, researchers recommend also have lower or even no opposite transactions for Sunday than with other days, because there is no connection between grocery sales and Saturdays and Sundays.

A researcher wants to construct a 90% confidence interval for the proportion of elementary school students in Seward County who receive free or reduced-price school lunches. A state-wide survey indicates that the proportion is 0.50. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.1?

Answers

Answer:

The sample  size is  [tex]n =68[/tex]

Step-by-step explanation:

    The population proportion is  [tex]\^ p = 0.50[/tex]

     The margin of error is  [tex]E = 0.1[/tex]

From the question we are told the confidence level is  90% , hence the level of significance is    

      [tex]\alpha = (100 - 90 ) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645 [/tex]

Generally the sample size is mathematically represented as  

    [tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]

=>  [tex]n = [\frac{1.645 }{0.1} ]^2 * 0.50  (1 - 0.50 ) [/tex]

=>  [tex]n =68[/tex]

     

The first coordinate of the point ( - 3, 2) indicates the point is located

Answers

Answer:

In the first coordinate

Step-by-step explanation:

For x = -3, the point is either located in 2nd or 3rd quadrant.

What is the general equation of a Straight line? What is a coordinate?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

A coordinate is represented as -

P(x, y)

where -

[x] is abscissa

[y] is ordinate

We have the following coordinate -

(-3, 2)

For x = -3, the point is either located in 2nd or 3rd quadrant

Therefore, for x = -3, the point is either located in 2nd or 3rd quadrant.

Solve for n in the following equation. A=P(1+n) show all your work

Answers

Answer:

A-1/P=n

Step-by-step explanation:

step 1. look at the parentheses and use inverse operations on both sides

A=P(1+n)

-1       -1

step 2. divide both sides by P

A-1=P(n)

/P    /P

n= A-1/P

The value of n on solving the equation A = P (1 + n) is A / P - 1.

What is equation?

An assertion that two mathematical expressions have equal values is known as an equation. An equation simply states that two things are equal. The equal to sign, or "=," is used to indicate it.

Given:

A = P (1 + n),

Here we can solve the parentheses by using the distributive property as shown below,

A = P × 1 + P × n

A = P + nP

Transform as shown below,

nP = A - P

n = (A - P) / P

n = A / P - 1

Thus, the value of n is A / P - 1.

What would be the best first step to convert 5x-y=7 to slope intercept form?

Question 1 options:

Multiply both sides by -1


-5x from both sides


+5x to both sides


Subtract 7 from both sides

Answers

Answer:

-5x from both sides

Step-by-step explanation:

When converting an equation to slope-intercept form, you need to isolate the y. The first step in isolating the y is to remove 5x from both sides of the equation:

5x - y = 7

5x - 5x - y = 7 - 5x

-y = 7 - 5x

Now it's just -1y on one side of the equation.

Subtract 5x from both sides
