Answer:

The given function is

$y=5.5x$

This is a linear function, where $y$ represents the total numbers of calories and $x$ represents the number of strawberries she was eating.

According to the given function, each strawberry has 5.5 calories.

It's important to notice that the graph of this function is a straight line which passes through the origin of the coordinate system, because it doesn't have a constant term.

The image attached shows the graph of the given function.

Therefore, the right graph is the one that intersects the origin of the coordinate system.

A building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18 \pi18π18, pi

katrin [286]

The area of the cross section of the column is $18 \pi \ m^2$

Explanation:

Given that a building engineer analyzes a concrete column with a circular cross section.

Also, given that the circumference of the column is $18 \pi$ meters.

We need to determine the area of the cross section of the column.

The area of the cross section of the column can be determined using the formula,

$Area= \pi r^2$

First, we shall determine the value of the radius r.

Since, given that circumference is $18 \pi$ meters.

We have,

$2 \pi r=18 \pi$

$r=9$

Thus, the radius is $r=9$

Now, substituting the value $r=9$ in the formula $Area= \pi r^2$ , we get,

$Area = \pi (9)^2$

$Area = 81 \pi$

Thus, the area of the cross section of the column is $18 \pi \ m^2$

Roper is not using a simple random sample. The samples are calculated to get 500 males and 500 females. This would be very unlikely or improbable to take place in a simple random sample. The design that they are using is a stratified sampling (dividing the population into groups) with 2 strata and these are the males and females.

Find the hcf of 144 and 180. if it is expressed in the form 13m-3, find the value of m

BaLLatris [955]

Answer:

Step-by-step explanation:

To find the HCF of 144 and 180

By using product of prime method

Firstly express 144 as a product of it prime and express 180 as a product of it prime

140=2×2×2×2×3×3

180=2×2×3×3×5

Common factor =2×2×3×3

in term of m

m=36

13m-3

To find m

Substitute for m when m=36

13(36)-3=

Alex Ar [27]

Answer:

There are 11550 possible selections

Step-by-step explanation:

Given

$Men = 7$

$Women = 11$

Required

How many ways can 4 men and 4 women be selected

The keyword in the question is SELECTION and it means COMBINATION;

So, number of selection is:

$Number = Men * Women$

$Number = ^7C_4 * ^{11}C_4$

This gives

$Number = \frac{7!}{(7-4)!4!} * \frac{11!}{(11-4)!4!}$

$Number = \frac{7!}{3!4!} * \frac{11!}{7!4!}$

$Number = \frac{7 * 6 * 5 * 4!}{3!4!} * \frac{11 * 10 * 9 * 8 * 7!}{7!4!}$

$Number = \frac{7 * 6 * 5}{3!} * \frac{11 * 10 * 9 * 8}{4!}$

$Number = \frac{7 * 6 * 5}{3 * 2 * 1} * \frac{11 * 10 * 9 * 8}{4 * 3 * 2 * 1}$

$Number = \frac{7 * 6 * 5}{6} * \frac{11 * 10 * 9 * 8}{4 * 3 * 2 * 1}$

$Number = 7 * 5 * \frac{11 * 10 * 9 * 8}{4 * 3 * 2 * 1}$

$Number = 7 * 5 * \frac{7920}{24}$

$Number = 7 * 5 * 330$

$Number = 11550$

Hence;

<em>There are 11550 possible selections</em>

6[4x(72-63) divided by 3]

spin [16.1K]

Answer:

Step-by-step explanation:

When an expression contains more than one sign, the rule of BODMAS is applied. Bracket of Division Multiplication Addition and Subtraction. And the signs will be solved in that order.

6[4x(72-63) divided by 3]

We solve the bracket first

(72-63)

The next is multiplication, inside the bigger bracket.

6[4x9 divided by 3]

Then division
