Pre-Alg

Order of Operations: BPEMDAS

Alg I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-2, 1)

Point (2, -5)

Step 2: Find slope m

Substitute: $m=\frac{-5-1}{2-(-2)}$
Simplify: $m=\frac{-5-1}{2+2}$
Subtract/Add: $m=\frac{-6}{4}$
Simplify: $m=\frac{-3}{2}$

The time needed for all college students to complete a certain paper-and-pencil maze follows a normal distribution with a popula

oee [108]

Answer:

The correct option is a

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 30\ seconds$

The standard deviation is $\sigma = 3 \ seconds$

The sample size is n = 9

The null hypothesis is $H_o: \mu = 30$

The alternative hypothesis is $H_a : \mu \ne 30$

The level of significance is $\alpha = 0.01$

The sample mean is $\= x = 31.2$

Generally the test statistics is mathematically represented as

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

=> $z = \frac{ 31.2 - 30}{ \frac{3}{\sqrt{9} } }$

=> $z = 1.2$

From the z table the area under the normal curve to the right corresponding to 1.2 is

$P(Z > 1.2) = 0.11507$

Generally the p-value is mathematically represented as

$p-value = 2 * P(Z > 1.2)$

=> $p-value = 2 *0.11507$

=> $p-value = 0.230$

From the value obtained w can see that

$p-value > \alpha$ hence

The decision rule is

Fail to reject the null hypothesis

The conclusion is there is not enough evidence to support the claim

three times a number is subtracted from another number and the difference is 3. The sum of the two numbers is 31. What is the sm

Aleksandr-060686 [28]

ANSWER

The smaller number is 7.

EXPLANATION

Let the numbers be x and y.

Then we have;

y-3x=3... eqn (1)

If the sum of the numbers is 3 then,

y+x=31... eqn (2)

Eqn(2) - Eqn (1)

x--3x=31-3

$4x = 28$

Divide both sides by 4,

$x = 7$

We put x=7 into the second equation,

y+7=31

y=31-7

y=24

The smaller of the two numbers is 7.
