Hi

So, we know the 1 inch = 5 miles
Multiply

2 7/16 x 5 = ?
Round down
2 x 5 = 10

The answer is a. 10

Hope this helps! :)

A manager finds a moderate negative correlation between the number of computer sales and the number of microwave sales in his st

eduard

The true statement is the correlation is most likely due to a lurking variable.

<h3>What is negative correlation?</h3>

Correlation is a statistical measure used to measure the relationship that exists between two variables. Negative correlation is when there is an inverse relationship between the two variables. If one variable increases, the other variable decreases.

Assume that the store is located near a school where the students live on an allowance. So, students do not have time to buy both computers and microwaves. When students buy computers they do not have enough money to buy microwaves. This explains the negative correlation.

Answer:

$\boxed{\bf \: \cfrac{13}{5}}$

<u>Or in Decimal:</u>

$\boxed{\bf \: 2.6}$

Step-by-step explanation:

<u>Given expression :-</u>

$\sf \: ( 26 \div 100) \times 10$

<u>Solution :-</u>

$\sf = (26 \div 100 )\times 10$

This arithmetic expression may be rewritten as ;

$\sf = \cfrac{26}{100} \times 10$

Step 1 : <u>Cancel the zero of 10 and one zero of 100</u> :-

$\sf = \cfrac{26}{10 \cancel0} \times 1 \cancel0$

<em>Results to;</em>

$\sf = \: \cfrac{26}{10} \times 1$

$\sf = \: \cfrac{26}{10}$

Step 2: <u>Cancel 26 and 10</u><u> </u><u>by 2</u> :-

$\sf = \cfrac{ \cancel{26}}{ \cancel{10}}$

<em>Results to;</em>

$\sf = \cfrac{ \cancel{26} {}^{13} }{ \cancel{10} {}^{5} }$

$\sf = \cfrac{13}{5}$

<em>It can also be in Decimal.</em>

That is;

$\sf = 2.6$

Hence, the answer of the expression would be 13/5 or 2.6 .

$\rule{225pt}{2pt}$

I hope this helps!

I am joyous to help!

The two-way frequency table below shows data on student behavior and the use of positive phone calls home as an incentive for go

dusya [7]

Answer:

From the frequency table, let's calculate the row total.

Row total for phone call = 19 + 9 = 28

Row total for no phone call = 8 +6 = 14

To calculate their respective row relative frequencies, let's use:

Row relative freq = $\frac{freq.}{Row total}$

Now, the two-way frequency table will be computed as:

For phone call:

Desirable behavior = $\frac{19}{28} = 0.67857$ ≈0.69

Undesirable behaviour = $\frac{9}{28} = 0.3214$ ≈0.32

No phone call:

Desirable behaviour = $\frac{8}{14} = 0.5714$ ≈ 0.57

Undesirable behaviour = $\frac{6}{14} = 0.4286$ ≈ 0.43

The complete two-way table is attached.

(14+42-6)/10+7^2 order of operation

Rainbow [258]

Answer:

54

Step-by-step explanation:

$\dfrac{(14+42-6)}{10}+7^2$

Parentheses (14 + 42 - 6) = 50:

⇒ 50/10 + 7²

Exponents 7² = 49:

⇒ 50/10 + 49

Multiplication/division 50/10 = 5:

⇒ 5 + 49

Addition/subtraction: 5 + 49 = 54

⇒ 54
