Harold works at a men,s clothing store which marks up its retail clothing by 27%. The store purchases pants for 74.00 suit jackets for 325.00 and dress shirts for 48.00 how much will Harold charge a customer for two pairs of pants ,three dress shirts and a suit jacket?

Y= Retail price
X= Purchase Price

Formula: Y= X(1 + 0.27)

Pants: $74.00 x 1.27 = 93.98

Dress: $325.00 x 1.27 = 412.75

Shirt: 48.00 x 1.27 = 60.96

2 pants: $93.98 x 2 = $187.96

3 dresses: $412.75 x 3 = $1,238.25

1 suit jacket: $60.96 x 1 = $60.96

187.96
1,238.25
+ 60.96
1,487.17

Harold would charge a customer $1,487.17 for two pairs of pants, three dress shirts and a suit jacket at a markup price of 27%

According to a survey, the average American person watches TV for 3 hours per week. To test if the amount of TV in New York City

Neporo4naja [7]

Answer:

Test statistic (t-value) of this one-mean hypothesis test is -2.422.

Step-by-step explanation:

We are given that according to a survey, the average American person watches TV for 3 hours per week. She surveys 19 New Yorkers randomly and asks them about their amount of TV each week, on average. From the data, the sample mean time is 2.5 hours per week, and the sample standard deviation (s) is 0.9 hours.

We have to test if the amount of TV in New York City is less than the national average.

Let Null Hypothesis, $H_0$ : $\mu$ $\leq$ 3 {means that the amount of TV in New York City is less than the national average}

Alternate Hypothesis, $H_1$ : $\mu$ > 3 {means that the amount of TV in New York City is more than the national average}

The test statistics that will be used here is One-sample t-test statistics;

T.S. = $\frac{\bar X - \mu}{\frac{s}{\sqrt{n} } }$ ~ $t_n_-_1$

where, $\bar X$ = sample mean time = 2.5 hours per week

$s$ = sample standard deviation = 0.09 hours

n = sample size = 19

So, test statistics = $\frac{2.5 - 3}{\frac{0.9}{\sqrt{19} } }$ ~ $t_1_8$

= -2.422

Therefore, the test statistic (t-value) of this one-mean hypothesis test (with σ unknown) is -2.422.

Karen says every equilateral triangle is acute.is this true explain

goblinko [34]

Hey there!

An equilateral triangle is a triangle that has all equal sides and angles. All the angles in a triangle equal 180 degrees. All triangles have 3 angles. 180/3=60 Each angle in an equilateral triangle is equal to 60 degrees. Acute angles are less than 90 degrees, so: 60<90. This makes every equilateral triangle acute.

I hope this helps!
