When you bring something up or move something down, you have to multiply the exponent by -1. So in this case, you are bringing up the exponent. Multiply 5 by -1 and your answer should be x^5/1.

15. The height and yolume of a cylinder are 4cm and 616cm respectively. Calculate the diameter of the base. (take t = 27 쪽 A. 7c

irakobra [83]

Step-by-step explanation:

Given that,

Height of cylinder = 4 cm
Volume of cylinder = 616 cm³

To find,

Diameter of the base = ?

Firstly we'll find the base radius of the cylinder.

$\longmapsto\rm{V_{(Cylinder)} = \pi r^2h}\\$

According to the question,

$\longmapsto\rm{616= \dfrac{22}{7} \times r^2 \times 4}\\$

$\longmapsto\rm{616 \times 7 = 22 \times r^2 \times 4}\\$

$\longmapsto\rm{4312 = 88 \times r^2 }\\$

$\longmapsto\rm{\cancel{\dfrac{4312}{88}} = r^2 }\\$

$\longmapsto\rm{49 = r^2 }\\$

$\longmapsto\rm{\sqrt{49} = r }\\$

$\longmapsto\rm{7 \; cm = r }\\$

Now,

$\longmapsto\rm{Diameter = 2r }\\$

$\longmapsto\rm{Diameter = 2(7 \; cm) }\\$

$\longmapsto\bf{Diameter = 14 \; cm}\\$

The required answer is 14 cm.

In a conventional gradient, the amount of money in period one is known as the_________.

erik [133]

In a conventional gradient, the amount of money in period one is known as the base amount.

<h3>What is an arithmetic gradient? </h3>

An arithmetic gradient series is a cash flow series that either increases or decreases by a constant amount each period.

<h3>What is a base amount?</h3>

Base amount is the fundamental numerical assumption from which something is begun or estimated in a given arithmetic series. It usually occurs in period for a conventional gradient.

Thus, in a conventional gradient, the amount of money in period one is known as the base amount.

Amanda earned a score of 940 on a national achievement test that was normally distributed. The mean test score was 850 with a st

Sindrei [870]

First, to find out the number of students who scored below Amanda, we must find the z-score value of Amanda's score using the formula below.

$Z = \frac{(\chi - \mu)}{\sigma}$

where Z is the z-score, Χ is the expected average value, μ is the mean of Χ, and δ is the standard deviation. Thus, we have

$Z = \frac{(940 - 850)}{\sqrt{100}}$
$Z = 0.90$

Thus, using the z-table, we have P(Z<0.90) = 0.8159. Since we have wanted to find the number of students who scored below Amanda, then from the whole, we have (1 - 0.8159) = 0.1841. That means, out of 1000 students, 0.1841 of them scored below Amanda. Thus, we have (0.184)(1000) = 184.

Answer: 184 students
