Answer:

I believe that a bar graph will help with that, because you can narrow the answers down to a bar graph and a line graph but a line graph will only show an increase and a decrease not an average, and a bar graph shows all three.

Answer:

B. $10

Step-by-step explanation:

Camila's employer pays 90% of the total cost of her family's health insurance

plan

Therefore, Camilla pays only 10%

If the total cost of the plan increases from $850 per month to $950 per month, how much more will Camilla have to pay

each month?

Amount of health insurance Camilla pays at $850 per month = 10% of $850

= 0.1 * $850

= $85

Amount of health insurance Camilla pays at $950 per month = 10% of $950

= 0.1 * $950

= $95

Amount Camilla pays more = $95 - $85

= $10

24/10 = 2.4

You need 3 cooks to make the large cakes.

In 2 hours

1 cook makes 28 small cakes

130/28 = 4.64

You need 5 cooks to make the small cakes.

IQR is shorthand for interquartile range

=========================================================

Explanation:

The original list is {84,75,90,87,99,91,85,88,76,92,94}

It sorts to {75,76,84,85,87,88,90,91,92,94,99}

Pick out the middle most value, which is 88 in slot 6. A quick way to get here is to see that there are n = 11 values in this set. So n/2 = 11/2 = 5.5 which rounds to 6, and that tells us the slot number where the median is held. If n is an even number, then you'll need to use the midpoint formula for the two middle-most items.

After we determine the median is 88, we split the sorted data set as follows:

L = {75,76,84,85,87}

U = {90,91,92,94,99}

Everything in set L is below the median. L for lower.

Everything in set U is above the median. U for upper.

Sets L and U have 5 items each. Note that 5+1+5 = 11 = n.

-------------

The median of set L is 84, so Q1 = 84

The median of set U is 92, so Q3 = 92

Q1 and Q3 are the first and third quartiles respectively. Subtracting them gets us the IQR (interquartile range)

IQR = Q3 - Q1

IQR = 92 - 84

IQR = 8

The IQR helps give us a sense how spread out the data set is. It's similar to the range, which is found by range = max - min. The larger the (interquartile)range, the more spread out the data set will be.

The expression 8x² + x is a polynomial.

Option C is the correct answer.

Polynomial is an equation written with terms of the form kx^n.

where k and n are positive integers.

There are quadratic polynomials and cubic polynomials.

Example:

2x³ + 4x² + 4x + 9 is a cubic polynomial.

4x² + 7x + 8 is a quadratic polynomial.

We have,

A polynomial is an algebraic expression with one or more terms, where each term has a non-negative integer exponent on the variable.

Among the given options,

Only the expression 8x² + x is a polynomial because it has two terms with non-negative integer exponents on the variable x.

The other options are not polynomials because:

"4x² – 3x +2/x" is not a polynomial because it has a term with a negative exponent on the variable.

"-6x² + x² – √5" is not a polynomial because it has a term with a non-integer exponent on the variable.

"-2x^4+3/2x" is not a polynomial because it has a term with a negative exponent on the variable.

Thus,

The expression 8x² + x is a polynomial.

Answer:

416 ft

Step-by-step explanation:

We will start with the easiest shape.

10 x 4 x 4 = 160

We will put that to the side and continue.

we see that 20 feet is the whole height of the object but since there is the height of 4 feet on the bottom shape, we will take 4 from 20 to give us 16 feet for the top shape.

16 x 4 x 4 = 256

Now, we add the totals.

256 + 160 = 416

Answer:

Answer:

V = 63944 in^3

Step-by-step explanation:

This shape is a rectangular prism.  The volume of such a prism is found by calculating V = (length)(depth)(height).  In this particular case,

                   V = (72.5 in)(24.5 in)(36 in)

             or:   V = 63944 in^3

Answer:

8 loaves

Step-by-step explanation:

so each loaf contains 7/8 cups flour

there are 7 loaves

7 ÷ 7/8 = 8

Answer:

1/8

Step-by-step explanation:

So if the entire recipe makes 7 loaves and calls for 7/8 of a cup, you would need to split the 7/8 cups flour into 7. 7/8 ÷ 7=1/8.

Answer:

no real answer

Step-by-step explanation:

distribute the -4 and combine all of the like terms on the left side = r-8-4r, then -8-3r

then we have 7-3r=-8-3r

from here, we can already tell that there's no real answer. this is because the two -3r will cancel, leaving no variable.

since 7 doesn't equal -8, there is no answer.

if, for example, the value on both sides of the equal sign were the same after the variable was eliminated, then your answer would be all real numbers

Answer:

Step-by-step explanation:

The slope of y = -5/4x + 4 is -5/4. The y-intercept is 4.

The slope of y=3/2x-7 is 3/2. The y-intercept is -7.

The distance between two points:

[tex] \large \boxed{ \sqrt{(x_2 - x_1)^{2} + {(y_2 - y_1)}^{2} } }[/tex]

From the graph, the given points are (-3,1) and (5,-4). Substitute the points in as we get:

[tex] \large{d = \sqrt{ {( - 3 - 5)}^{2} + {(1 + 4)}^{2} } } \\ \large{d = \sqrt{ { (- 8)}^{2} + {5}^{2} } } \\ \large{d = \sqrt{64 + 25} \longrightarrow \sqrt{89} } [/tex]

Hence the distance between two points is √89.
