Reflection is thinking back on something. Like I was reflecting on a story I read earlier. It could also be something that is seen on a mirror or on something that is shiny. I saw my reflection in the bathroom mirror.

An online furniture store sells chairs for $150 each and tables for $550 each. Every day, the store can ship a maximum of 40 pie

Katen [24]

Answer:

minimum of 13 chairs must be sold to reach a target of $6500

and a max of 20 chairs can be solved.

Step-by-step explanation:

Given that:

Price of chair = $150

Price of table = $400

Let the number of chairs be denoted by c and tables by t,

According to given condition:

t + c = 30 ----------- eq1

t(150) + c(400) = 6500 ------ eq2

Given that:

10 tables were sold so:

t = 10

Putting in eq1

c = 20 (max)

As the minimum target is $6500 so from eq2

10(150) + 400c = 6500

400c = 6500 - 1500

400c = 5000

c = 5000/400

c = 12.5

by rounding off

c = 13

So a minimum of 13 chairs must be sold to reach a target of $6500

i hope it will help you! mark me as brainliest pls

If anyone could answer this for me I would very much appreciate it

baherus [9]

Answer:

a3 = 45

Step-by-step explanation:

a1 = 20

an = a(n-1) *3/2 where n is the term number

a2 = a(2-1) *3/2

a1 *3/2

We know a1 = 20

a2 = 20*3/2 = 30

a3 = a(3-1) *3/2

= a2 *3/2

We know a2 = 30

= 30*3/2 = 45

A simple random sample of size nequals81 is obtained from a population with mu equals 83 and sigma equals 27. (a) Describe the

Ivanshal [37]

Answer:

a) $\bar X \sim N (\mu, \frac{\sigma}{\sqrt{n}})$

With:

$\mu_{\bar X}= 83$

$\sigma_{\bar X}=\frac{27}{\sqrt{81}}= 3$

b) $z= \frac{89-83}{\frac{27}{\sqrt{81}}}= 2$

$P(Z>2) = 1-P(Z$

c) $z= \frac{75.65-83}{\frac{27}{\sqrt{81}}}= -2.45$

$P(Z$

d) $z= \frac{89.3-83}{\frac{27}{\sqrt{81}}}= 2.1$

$z= \frac{79.4-83}{\frac{27}{\sqrt{81}}}= -1.2$

$P(-1.2$

Step-by-step explanation:

For this case we know the following propoertis for the random variable X

$\mu = 83, \sigma = 27$

We select a sample size of n = 81

Part a

Since the sample size is large enough we can use the central limit distribution and the distribution for the sampel mean on this case would be:

$\bar X \sim N (\mu, \frac{\sigma}{\sqrt{n}})$

With:

$\mu_{\bar X}= 83$

$\sigma_{\bar X}=\frac{27}{\sqrt{81}}= 3$

Part b

We want this probability:

$P(\bar X>89)$

We can use the z score formula given by:

$z = \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And if we find the z score for 89 we got:

$z= \frac{89-83}{\frac{27}{\sqrt{81}}}= 2$

$P(Z>2) = 1-P(Z$

Part c

$P(\bar X$

We can use the z score formula given by:

$z = \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And if we find the z score for 75.65 we got:

$z= \frac{75.65-83}{\frac{27}{\sqrt{81}}}= -2.45$

$P(Z$

Part d

We want this probability:

$P(79.4 < \bar X < 89.3)$

We find the z scores:

$z= \frac{89.3-83}{\frac{27}{\sqrt{81}}}= 2.1$

$z= \frac{79.4-83}{\frac{27}{\sqrt{81}}}= -1.2$

$P(-1.2$

PLEASE HELP ASAP. 6th grade. 20 POINTS PLEASE HELP!!!!!! Answers: -1,-2, -1/2, 2.

Murrr4er [49]

Answer:

The slope is -2.

Step-by-step explanation:

Slope formula:

$\displaystyle \frac{y_2-y_1}{x_2-x_1}$

$y_2=1\\\\y_1=3\\\\x_2=1\\\\x_1=0\\$

$\displaystyle\frac{1-3}{1-0}=\frac{-2}{1}=-2$

Therefore, the slope is -2, and the correct answer is -2.

Hope this helps!

Help with the question attached below

Keith_Richards [23]

Answer:

Exact volume = 294π in³

Approximate volume = 923.6 in³

Explanation:

The volume of a cylinder can be calculated using the following rule:

volume = πr²h

where r is the radius and h is the height of the cylinder

In the given cylinder:

radius = r = 7 in

height = h = 6 in

Substitute with the givens in the formula to get the volume:

Volume of cylinder = πr²h = π(7)²(6) = 294π in³ ≈ 923.6 in³ to the nearest tenth

Hope this helps :)
