Hatshy [7]

Answer:

jacket 80

shoes 32 and 16

shirt 9   , 8.04,   4.08

Step-by-step explanation:

you need to multiply the original cost by the percentage off and then subtract from the original

example

Jacket is originally priced at $120 it is on sale for 1/3 off which means that if you divide 120 by 3 you will get 40.  but you would have to subtract the 40 from 120 giving you 80

True… irrational numbers focus more around square roots that cant be simplified into a single number, or symbols like pi. while not all rational numbers are whole, an irrational number can never be whole.

mario62 [17]
<h2>Answer and Explanation:</h2><h2 />

The density of a substance is defined as its mass per unit volume. In a mathematical language, this can be written as follows:

\rho=\frac{m}{V} \\ \\ \\ Where: \\ \\ \rho: \ density \\ \\ m:mass \\ \\ V:Volume

From the problem, a student is trying to calculate the density of a ball. She already knows the mass, but is facing a problem because she also needs to find the volume. From geometry, we know that the volume of a sphere is:

V=\frac{4}{3} \pi r^{3}

Since a ball is a sphere, then the student can use this formula. She just need to measure the radius of the ball and compute the Volumen, then she have to plug both the value of the mass and the value of the Volume in the equation \rho=\frac{m}{V}. An easy way to find the radius is to take the measure of the diameter of the ball and divide that value by 2.

"Henri has calculated a z-test statistic of -2.73. What is the p-value of the test statistic? Answer choices are rounded to the
Novay_Z [31]

Answer:

0.003

Step-by-step explanation:

P-value = The value of probability.

P value can be defined are the probability of a given test statistic ( which could be z score, t score, f score) that is can be less than, equal to or greater than a given null hypothesis.

In the above question, the test statistic we are given = z score.

z score = -2.73

To find the P- value, we can make use of a z table for normal distribution.

Hence, P(z = -2.73) = 0.0031667

Approximately to the nearest thousandth = 0.003
