Answer: z > -9

Step-by-step explanation:

$\frac{-2z-3}{3} < 5$ multiply each side by 3 to get

-2z -3 < 15 now add 3 to both sides

+3 +3

-2z < 18 Divide both sides by -2. Since your dividing by a negative number the inequality sign will change

z> -9

How many five digit numbers can be formed from the digits 1,,3,4,5,6,7 if no digit is repeated

Viktor [21]

To get all possible permutations of these five spaces, we just multiply these numbers (that is, 8∗7∗6∗5∗4=6,720)

There are 6,720 five digit numbers that can be formed from the digits provided given that no digit may be repeated.

Hope that helped!

Use Cavalieri’s Principle to calculate the exact volume of an oblique cylinder with a height of 10 meters and a circular base wi

nirvana33 [79]

Answer: Volume of an oblique cylinder is 2011.43 sq.m.

Step-by-step explanation:

Since we have given that

Radius of a cylinder = 8 meters

Height of a cylinder = 10 meters

Cavelieri's Principle states that volume of an oblique cylinder is same as the volume of right circular cylinder with equal radius and height.

As we know the formula for "Volume of cylinder":

$Volume=\pi r^2h\\\\V=\frac{22}{7}\times 8\times 8\times10\\\\V=\frac{14080}{7}\\\\V=2011.43$

Hence, Volume of an oblique cylinder is 2011.43 sq.m.

Suppose the manager of a restaurant in a commercial building has determined that the proportion of customers who drink tea is 24

BartSMP [9]

Answer:

0.427

Step-by-step explanation:

Standard error for the sampling distribution refers to the standard deviation of the samples taken from a population. The standard error equals the standard deviation divided by the square root of the sample size

The probability of customers who drink tea (p) = 24% = 0.24, the sample size of customers (n) = 300.

Standard error = $\frac{\sigma}{\sqrt{n} }$ where σ is the standard deviation.

$\sigma=\sqrt{np(1-p)}$

Standard error = $\frac{\sigma}{\sqrt{n} }= \frac{\sqrt{np(1-p)} }{\sqrt{n} } =\sqrt{\frac{np(1-p)}{n} } =\sqrt{p(1-p)}=\sqrt{0.24(1-0.24)} =0.427$

What is the area of a 320 ft semicircle?

Sever21 [200]

Answer: they do not have enough info but I will try my best to answer if im wrong its not my fault so please add more info

Solution

2. I know that for a Semi-Circle Area = 320 . From this find out Area of the Semi-Circle.

Solution:

Here Area=320(Given)

Area=

πr2

r2=

Area⋅2

r2=

320⋅2

r=14.2701

Diameter(d)=2r

=2⋅14.2701

=28.5402

Circumference=πr

⋅14.2701

=44.849

Perimeter=πr+2r

⋅14.2701+2⋅14.2701

=44.849+28.5402

=89.6979
