Administrators at a large public high school are interested in their students’ standardized test scores. Last year, the mean sco
ratelena [41]

Answer:

The appropriate hypotheses for performing a significance test is:

H_0: \mu = 51

H_1: \mu > 51

Step-by-step explanation:

Last year, the mean score on the state’s math test was 51. The administrators have trained the teachers in a new method of teaching math hoping to raise the scores on this standardized test this year.

At the null hypothesis, we test if the mean score this year is the same as last year, that is:

H_0: \mu = 51

At the alternate hypothesis, we test if the mean score improved this year from last, that is:

H_1: \mu > 51

The appropriate hypotheses for performing a significance test is:

H_0: \mu = 51

H_1: \mu > 51

Two numbers are between 20 and 30. their greatest common factor is 4.Which two numbers could they be?
Andrew [12]
24 and 28
These are the only two numbers (other than 20 itself) that have a factor of 4. And if you were to find all of their common factors, 4 would be the greatest!

X = y+2<br> x+4y=7 <br><br> Please help!
spayn [35]
Since x = y + 2

so
y + 2 + 4y = 7

5y + 2 = 7

5y = 7-2

5y = 5

y = 1

x= y + 2

x = (1) + 2

x = 3

(x,y) = (3,1)

the adjacent sides parellelogram are 10cm and 8cm . if the perpendicular distance between the smaller sides are 6 cm the distanc
Art [367]

Answer:

The distance between the greater sides is 4.8 cm

Step-by-step explanation:

step 1

Find the area of parallelogram

we know that

the perpendicular distance between the smaller sides is also the height of parallelogram

The area of parallelogram is equal to multiply the length of the smaller side by the perpendicular distance between the smaller sides

so

A=8(6)=48\ cm^2

step 2

Find out the distance between the greater sides

we know that

The area of parallelogram is equal to multiply the length of the greater side by the perpendicular distance between the greater sides

Let

x ----> the perpendicular distance between the greater sides

so

A=10(x)

we have

A=48\ cm^2

substitute

48=10(x)

solve for x

x=4.8\ cm
