Answer:

$= \frac{11}{16}$

Step-by-step explanation:

$1 \frac{7}{8} \div 2 \frac{8}{11} \\ \frac{15}{8} \div \frac{30}{11} \\ \frac{15}{8} \times \frac{11}{30} \\ = \frac{165}{240} \\ = \frac{11}{16}$

Answer: 11/16

Turn 1 7/8 into an Improper Fraction

Multiply 1×8 and get 8. Now add 7 and get 15.

1 7/8 = 15/8

Turn 2 8/11 into an Improper Fraction

Multiply 2×11 and get 22. Now add 8 and get 30.

2 8/11 = 30/11

Do Keep Change Flip

Keep: 15/8

Change ÷ into ×

Flip: 30/11 into 11/30

Your New Problem: 15/8×11/30

Multiply

15/8×11/30=165/240

Simplify

165/240÷15/15=11/16

Three friends go to the local framers market. Latasha spends $3.35. Helen spends 4 times as much as Latasha. Dee spends $7.50 mo

mylen [45]

Given:

Latasha spends $3.35

Helen spends 4 times as much as Latasha.

Dee spends $7.50 more then Helen.

To find:

The amount Dee spends.

Solution:

It is given that, Latasha spends $3.35.

Helen spends 4 times as much as Latasha.

So, Helen spends = 4 × $3.35

= $13.40

Dee spends $7.50 more then Helen.

Dee spends = $13.40+$7.50

= $20.90

Therefore, dee spends $20.90.

In a study with four groups and 10 participants in each group, the sum of squares for the between-groups source of variation is

Stells [14]

Answer:

Step-by-step explanation:

Given that:

The study group n = 4

number of participants = 10

the sum of squares for the between-groups source of variation is 60

The objective is to determine the mean square between groups in this study

The mean square between groups in this study compares the means of the group with the sum of squares for the between-groups source (i.e the grand mean)

For this analysis;

the degree of freedom = n-1

the degree of freedom = 4 - 1

the degree of freedom = 3

Thus; the mean square between groups = $\dfrac{60}{3}$

the mean square between groups = 20
