B. A nonresponse error was made in this design. This type of sampling only represents the parents at this school and not the entire population.
C. A convenience sample error was made in this design. This type of sampling only represents the parents with e-mail addresses and not the entire population.
D. An undercoverage error was made in this design. This type of sampling only represents the parents in the city and not the entire population.

Answer:

A

Step-by-step explanation:

The design of the survey leads to bias because a nonresponse error was made in this design. This type of sampling only represents those who answered the survey; it does not represent the entire population.

Only 56% of response were received this means the entire population did not participate in the survey only a chuck of them answered the survey. This can lead to a biased result, an assumption.

What function represents a reflection f(x)=3/7(2)^x over the x-axis
Oksana_A [137]

Answer:

Given the function:

y=f(x)= \frac{3}{7}(2)^x

The rule of reflection across the x-axis is given by:

(x, y) \rightarrow (x, -y)

Apply the reflection over the x-axis on the given function we have;

-y = \frac{3}{7}(2)^x

Multiply both sides by -1 we get;

y=-\frac{3}{7}(2)^x

or

f(x)=-\frac{3}{7}(2)^x

Therefore, function represents a reflection f(x)=3/7(2)^x over the x-axis is, -\frac{3}{7}(2)^x

The school band has a goal of raising $800 for some new uniforms. If they have raised $512 so far, what percent of their goal ha
just olya [345]

Answer: 64%

Step-by-step explanation:

The band needs $800 for new uniforms and of that, they only raised $512.

Set up a proportion \frac{part}{total} = \frac{percentage}{100}and plug everything you know in.

\frac{512}{800} = \frac{x}{100}

Solve for x by cross multiplying and dividing.

512 × 100 = 51200

51200 ÷ 800 = 64

x = 64

The school band has raised 64% of their goal already.

A milk bottle has radius 7cm and milk is filled upto a height
stich3 [128]

radius of bottle is 7 cm. height is 28 cm

so total milk in bottle is equal to total volum of bottle.

so volume of cylinder is = pi × r^2 × h

V = (22/7 )× 7×7×28 = 22×7×28

= 4312 cm^3

so volume of the milk before used to make tea is 4312 cm^3

now milk taken to make tea make height reduced to 20 cm.

so volume of the left milk in bottole is

= (22/7) × 7×7×20 = 22×7×20

= 3080 cm^3

so milk used for making tea = total milk before making the tea - total milk left in bottle after making the tea

= 4312 - 3080 = 1232 cm ^3

so volume of milk used
