Answer:

Letter Grade: B Percentage: 80-89

Step-by-step explanation:

You got 216/250, so divide 216/250 and you get 0.864. This means 216 is 86.4 percent of 250 :)

Answer:

m=-2/5

Step-by-step explanation:

Slope is rise over run. In this graph the slope is negative because rise (change in the Y value) is decreasing.

A certain intelligence test has an N(100, 100) distribution. To see whether intelligence is inherited, tests are given to the el

Anettt [7]

Answer:

Follows are the solution to the given choices:

Step-by-step explanation:

In choice a:

$\to \mu = 100$

In choice b:

$\to \mu \neq 100$

In choice c:

$\to \ pop \ average=100 \\\\ \to \ variance \ of \ pop = 100 \\\\\to pop \ \ \sigma = \sqrt {(!00)} \\$

= 10

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

$=\frac{(105-100)}{\frac{10}{ \sqrt(16)}}\\\\=\frac{(5)}{ \frac{10}{4}}\\\\=\frac{5}{ \frac{5}{2}}\\\\= \frac{10}{5}\\\\=2$

$\to p==2\times (1- \ righttail)\\\\\to \ righttail\ \ p = \text{NORM.S.DIST(2,TRUE)}$

$=0.977249868$

$\therefore \\P=2 \times (1-0.9772)\\\\P=0.0455\\\\P$

Null hypothesis to dismiss

Alternate solution assumptions embrace

There is really no valid proof at the 5% stage that

Knowledge is legacy

In choice d:

Possibly information such as this reflect a sample population with such a true p = 0.0455 meaning in the hypothesis

u is around 100.

Two straight lines have equations y = p x + 4 y = p x + 4 and p y = q x − 7 p y = q x − 7 , where p p and q q are constants. The

kolbaska11 [484]

Answer:

q = $\frac{8}{3}$

Step-by-step explanation:

The point of intersection (3, 1 ) is the solution to both equations

Using

y = qx - 7 and substituting x = 3, y = 1

1 = 3q - 7 ( add 7 to both sides )

8 = 3q ( divide both sides by 3 )

$\frac{8}{3}$ = q

Which number produces an irrational number when multiplied by 1/3

MArishka [77]

We can simply observe that.

0.777... is rational, because it is a number with infinite but repeating decimal part.
1/3 is rational, because it's the division between two integers
$-\sqrt{16}=-4$ , so this is rational as well.

Since the product of two rational numbers is always rational, we have that

$0.\bar{7}\cdot \dfrac{1}{3},\quad \dfrac{1}{3}\cdot \dfrac{1}{3},\quad -4\cdot \dfrac{1}{3}$

are all rationals, since they are the product of two rationals.

On the other hand, we have

$\sqrt{27}=\sqrt{9\cdot 3}=3\sqrt{3}$

and thus

$3\sqrt{3}\cdot \dfrac{1}{3}=\sqrt{3}$

which is irrational.
