Answer:

The total area of Ohio is about 30 times the total area of Rhode Island

Step-by-step explanation:

Let

x -----> the total area of Ohio in square miles

y -----> the total area of Rhode Island in square miles

we know that

$x=4.5*10^{4}\ mi^{2}$

$y=1.5*10^{3}\ mi^{2}$ (<em>searched in Google</em>)

To find out approximately how many times the total area of Ohio is compared to the area of Rhode Island, divide the area of Ohio by the area of Rhode Island

$\frac{x}{y}$

substitute the values

$\frac{4.5*10^{4}}{1.5*10^{3}}=(\frac{4.5}{1.5})( 10^{4-3}) =3*10^{1}=30$

therefore

The total area of Ohio is about 30 times the total area of Rhode Island

two parallel lines are graphed on a coordinate plane.how many of the lines could represent proportional relationship?Explain.

soldi70 [24.7K]

It's not necessary that either one represents a proportional
relationship. But if either one does, then the other one doesn't.
They can't both represent such a relationship.

The graph of a proportional relationship must go through
the origin. If one of a pair of parallel lines goes through
the origin, then the other one doesn't. (If two parallel lines
both went through the origin, then they would both be the
same line.)

Rick bought 3 shirts for $18 each, 2 pair of socks for $3.99 a pair, and a pair of slacks, for $45.00. The sales tax is 8.5%. Ho

ivolga24 [154]

Price of 3 shirts=$18*3=$54
Price of 2 pair of socks=2*$3.99=$7.98
Price of a pair of slack=$45
Total amount- $54+$7.98+ $45-$106.98
Sales tax rate = 8.5%
8.5% of total amount-8.5% of $106.98=
(8.5/100)*106.98-9.0933
Total amount Rick paid=$106.98+9.0933=$116.0733

Three potential employees took an aptitude test. each person took a different version of the test. the scores are reported below

timama [110]

Answer:

Vincent and Reyna.

Step-by-step explanation:

As z-score indicates that a data point is how many standard deviation above mean, so to find which of three applicant should be offered the job, let us find the z-score for each person using z-score formula.

$z=\frac{x-\mu}{\sigma}$ , where,

$z$ = z-score,

$x$ = Random sample score,

$\mu$ = Mean,

$\sigma$ = Standard deviation.

$\text{z-score for Vincent}=\frac{83.5-68.2}{9}$

$\text{z-score for Vincent}=\frac{15.3}{9}$

$\text{z-score for Vincent}=1.7$

Therefore, Vincent's score on aptitude test is 1.7 standard deviation above mean.

$\text{z-score for Kaitlyn}=\frac{251.2-238}{22}$

$\text{z-score for Kaitlyn}=\frac{13.2}{22}$

$\text{z-score for Kaitlyn}=0.6$

Therefore, Kaitlyn's score on aptitude test is 0.6 standard deviation above mean.

$\text{z-score for Reyna}=\frac{8.04-7.2}{0.7}$

$\text{z-score for Reyna}=\frac{0.84}{0.7}$

$\text{z-score for Reyna}=1.2$

Therefore, Reyna's score on aptitude test is 1.2 standard deviation above mean.

Since Vincent and Reyna has higher z-scores, therefore, they are further above mean than Kaitlyn. Therefore, Vincent and Reyna should be offered the job.
