It’s b!

the line that is negative is dashed meaning the symbol isn’t less then or equal to the symbol is just less than! that’s why it’s not a! because the other line isn’t dotted, which means the equation for the line is y is less than or equal to something

In year 3 it is expected that the total value of clothing sales will reach 32 million if the total value of ASCO sells Remains t

aivan3 [116]

Answer:

The sales account for year 3 is $[\frac{32\ \text{mn}-x\ \text{mn}}{x\ \text{mn}}\times 100\%]$ .

Step-by-step explanation:

As the sales for year 2 is not provided, assume it is x million.

The total sales in year 3 is, 32 million.

Compute the sales account for year 3 as follows:

$\text{Percentage of sales for year 3}=\frac{\text{Total Sales in year 3}-\text{Total Sales in year 2}}{\text{Total Sales in year 2}}\times 100\%$

$=\frac{32\ \text{mn}-x\ \text{mn}}{x\ \text{mn}}\times 100\%$

The graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.

marshall27 [118]

Please consider the graph.

We have been given that graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic. We are asked to choose the weights, which are within 2 standard deviations of the mean.

We can see from our graph that mean of the weights is 9.5 and standard deviation in 0.5.

The data point that would be below two standard deviation is: $9.5-2\times 0.5$ that is $9.5-1=8.5$ .

The data point that would be above two standard deviation is: $9.5+2\times 0.5$ that is $9.5+1=10.5$ .

Now we need to check the data points that lie within 8.5 and 10.5.

Upon looking at our given choices, we can see that 8.9, 9.5 and 10.4 pounds lie within 2 standard deviation of the mean.

Therefore, 8.9 lbs, 9.5 lbs and 10.4 lbs are correct choices.

given that (y+2) (y+3) and (2y^2+1) are consecutive terms of an arithmetic progression, find the possible value of y

mafiozo [28]

Answer:

-3/2 and 1

Step-by-step explanation:

Given the arithmetic sequence (y+2) (y+3) and (2y²+1), the common difference is gotten by taking the difference in their terms. For example if we have 3 terms T1, T2, T3... the common difference d = T2-T1 = T3-T2

From the sequence given;

T1 = y+2, T2 = y+3 and T3 = 2y²+1

d = y+3-(y+2) = 2y²+1- (y+3)

open the parenthesis

y+3-y-2 = 2y²+1- y-3

1 = 2y²+1- y-3

1 = 2y²- y-2

2y²- y-2-1 = 0

2y²- y-3 =0

Factorize the resulting expression

2y²- y-3 =0

2y²- 2y+3y-3 =0

2y(y-1)+3(y-1) = 0

(2y+3)(y-1) = 0

2y+3 = 0 and y-1 = 0

2y = -3 and y =1

y = -3/2 and 1

Hence the possible values of y are -3/2 and 1

Using your answer from part (b) and inequality symbols, write one statement that shows the relationship among all of the numbers

Natali5045456 [20]

Answer:

(b) Least to greatest numbers are -1.0, $-\frac{1}{4}$ , 0, 0.5, 1.5

1.5 > 0.5 > 0 > $-\frac{1}{4}$ > -1.0

Step-by-step explanation:

P.S - The exact question is -

Given - Kendra collected data for her science project. She surveyed

people asking them how many hours they sleep during a

typical night.

The chart below shows how each person’s response compares

to 8 hours (which is the answer she expected most people to say).

Name Number of Hours Compared to Hours

(usually slept each night)

Frankie 8.5 0.5

Mr. Fields 7 −1.0

Karla 9.5 1.5

Louis 8 0

Tiffany $7\frac{3}{4}$ $-\frac{1}{4}$

To find - (a) Plot and label each of the numbers in the right-most column

of the table above on the number line below.

(b) List the numbers from least to greatest.

write one statement that shows the relationship among all

of the numbers.

Proof -

(a)

We can see that the numbers in the right-most column are 0.5, -1.0, 1.5, 0, $-\frac{1}{4}$

We can write $-\frac{1}{4}$ = -0.25

Now,

We have to label them in the number line

The number line is as follows :

(b)

Least to greatest numbers are -1.0, $-\frac{1}{4}$ , 0, 0.5, 1.5

(c)

By using inequality symbol, we get

-1.0 < $-\frac{1}{4}$ < 0 < 0.5 < 1.5

1.5 > 0.5 > 0 > $-\frac{1}{4}$ > -1.0

Which of the following angles is NOT congruent to 6? 3 2 7 1

TiliK225 [7]

Answer:

Step-by-step explanation:

We can see that 7 is equal to 6, as opposite angles are the same.

We can also see that 2 is also 6, as corresponding angles are equivalent.

Therefore, 3 is also congruent to 6, as it is equal to 2.

Hope that this helps!
