x - variable
8 - constant

The number 2 is not a coefficient in the expression. FALSE.
The expression has three terms. FALSE. two terms only: 2x & 8
The variable in the expression is x. TRUE
The number 2 is a constant in the expression. FALSE
The expression has one variable term. FALSE. 2x is term but it's a combination of a number and a letter. Variable term is letter only.

Suppose that .06 of each of two populations possess a given characteristic. Samples of size 400 are randomly drawn from each pop

omeli [17]

Answer:

The correct answer to the following question will be "0.0367".

Step-by-step explanation:

The given values are:

$p1=p2=0.06$

$q1=q2=1-p1=0.94$

$n1=n2=400$

As we know,

$E(p1-p2)=p1-p2=0\\$

$SE(p1-p2)=\sqrt{\frac{p1q1}{n1}+\frac{p2q2}{n2}}$

On putting the given values in the above expression, we get

$= \sqrt{p1q1(\frac{1}{400}+\frac{1}{400})}$

$=0.0168$

Now, consider

$P(p1-p2>0.03)=P[\frac{(p1-p2)-E(p1-p2)}{SE(p1-p2)}>\frac{0.03-0}{0.0168}]$

$=P(Z>1.7857)$

$=P(Z>1-79)$

$=0.036727$

Therefore, "0.0367" is the right answer.

For what value of h is 24=(h/10)-6

kondor19780726 [428]

Answer:

$h=300$

Step-by-step explanation:

we have

$24=(\frac{h}{10})-6$

Solve for h

That means----> Isolate the variable h

Adds 6 both sides

$24+6=(\frac{h}{10})-6+6$

$30=\frac{h}{10}$

Multiply by 10 both sides

$30*10=\frac{h}{10}*(10)$

$h=300$

Susie has 34 nickels and dimes. Their total value is $2.35. How much of each does she have?

Dennis_Churaev [7]

Given:

Susie has 34 nickels and dimes. Their total value is $2.35.

To find:

The number of nickels and number of dimes.

Solution:

Let the number of nickels be x and number of dimes be y.

Susie has 34 nickels and dimes.

$x+y=34$ ....(i)

We know that,

1 nickel = $0.05

1 dime = $0.10

Their total value is $2.35.

$0.05x+0.10y=2.35$

Multiply both sides by 100.

$5x+10y=235$

Divide both sides by 5.

$x+2y=47$ ...(ii)

Subtracting (i) from (ii), we get

$x+2y-x-y=47-34$

$y=13$

Putting y=13 in (i), we get

$x+13=34$

$x=34-13$

$x=21$

Therefore, number of nickels is 21 and number of dimes is 13.
