Answer:

$31.5

Step-by-step explanation:

The t-shirt is worth $42

$42 is 100% of the actual price or the real price of the t-shirt

25% off, means you subtract 25% of 42 off of the t-shirt, or you find 100% - 25% of the t-shirt

25% - 100% = 75%

75% of 42 = 0.75 * 42 = 31.5

The sale price of the t-shirt is $31.5

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below
gavmur [86]

Answer:

Tobias did best on the aptitude test.

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

For Emilio

Emilio got a score of 76; this version has a mean of 70.6 and a standard deviation of 9.

z = (x-μ)/σ

z = 76 - 70.6/9

z = 0.6

For Alissa

Alissa got a score of 298.8; this version has a mean of 282 and a standard deviation of 24.

z = (x-μ)/σ

z = 298.8 - 282/24

z = 0.7

For Tobias

Tobias got a score of 8.04; this version has a mean of 7.2 and a standard deviation of 0.4.

z = (x-μ)/σ

z = 8.04 - 7.2/0.4

z = 2.1

Looking at the calculated z score above, we can see that Tobias did better on his aptitude test because he had a higher z score compared to Emilio and Alissa.

Yes they are equivalent, because they both do 30 jumping jacks per minute. If you divide 60/2=30 & 150/5=30. Hope this helps!

The triangle was only rotated. The size did not change, so the corresponding angles would remain identical.

Because C is 28 degrees C' would also be 28 degrees.
