Answer: 242

Step-by-step explanation: base times height for rectangle = 168

and 1/2(base1+base2)h for trapezoid = 74

then add!

How do you simplify this using the laws of exponents?

STALIN [3.7K]

Answer:

x1 = x 61 = 6

x0 = 1 70 = 1

x-1 = 1/x 4-1 = 1/4

xmxn = xm+n x2x3 = x2+3 = x5

xm/xn = xm-n x6/x2 = x6-2 = x4

(xm)n = xmn (x2)3 = x2×3 = x6

(xy)n = xnyn (xy)3 = x3y3

(x/y)n = xn/yn (x/y)2 = x2 / y2

x-n = 1/xn x-3 = 1/x3

hompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 125 millimeters,

choli [55]

Answer:

$P(-2.012$

So since we want the probability that "the sample mean would differ from the population mean by greater than 2.2 millimeters". Then we use the complement rule and we got

P=1-0.9558=0.0442

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Let X the random variable that represent the diameter of a population, and for this case we know the distribution for X is given by:

$X \sim N(125,49)$

Where $\mu=125$ and $\sigma=7$

And let $\bar X$ represent the sample mean, the distribution for the sample mean is given by:

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

On this case $\bar X \sim N(125,\frac{7}{\sqrt{41}}=1.093)$

Solution to the problem

We can begin the problem finding this probability

$P(\mu -2.2$

We can use the normal standard distribution and the z score given by:

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

If we apply this formula to our probability we got this:

$P(125-2.2$

$=P(\frac{122.8-125}{\frac{7}{\sqrt{41}}}$

And we can find this probability on this way:

$P(-2.012$

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.

$P(-2.012$

So since we want the probability that "the sample mean would differ from the population mean by greater than 2.2 millimeters". Then we use the complement rule and we got:

P=1-0.9558=0.0442

Look at the steps used when solving <br>4(x – 3) = 8<br>

aliya0001 [1]

Answer:

4(x – 3) = 8

4x - 12 = 8 u multiply 4 by x and 3

4x = 8 + 12 u switch 12 to the other side to leave x alone and when doing that u change its symbol to - to +

4x = 20 now ur going to switch 4 to the other side and since its multiplication it going to change to division

x = 20/4

x= 5

Desarrollar por el metodo de reduccion: 1. si: { 3x+ 2y = 26 { 5x - y = 26 hallar: e= x +y

Ahat [919]

We got the value of $e=\frac{78}{7}$ by solving the given equations $3x+2y=26$ and $5x+y=26$ by reduction method.

<h2>What is reduction method?</h2>

The reduction or elimination approach includes using arithmetic operations between equations to produce equivalent equations with fewer unknowns that are simpler to analyze and evaluate.

Given equations are

$3x+2y=26$ .........(1)

$5x+y=26$ ...........(2)

We need to find the value of $e=x+y$
