g You want to test whether a new commercial increases brand recognition. You use a one-week testing period to evaluate the new ad. The null hypothesis for the test, H0, will be:

Answer:

the 3rd one..........??

Answer:

Here,

f(x)=2x+3(x-3)

if f(x)=11

we know that,

or,11=2x+3(x-3)

or,11=2x+3x-9

or,11+9=5x

or,20=5x

Therefore,x=4

Answer:

x = 4

Step-by-step explanation:

2x + 3x - 9 = 11

5x = 11+9

5x = 20

x = 4

Complete Question

If the p-value for your test statistic in a test of hypothesis (for example, a t-test, one-tail) is 0.07 and the significance level alpha is set at 0.05, you conclude that:

A  

Both hypotheses H0 and H1 can be accepted

B

The null hypothesis H0 cannot be rejected

C

The null hypothesis H0 can be rejected

D

The research hypothesis H1 can be accepted

Answer:

The correct option is B

Step-by-step explanation:

From the question we are told that

     The p-value  is  [tex]p-value = 0.07[/tex]

     The level of significance is  [tex]\alpha = 0.05[/tex]

Generally given that it is a one tail test then the possible value of  

   The null hypothesis is  [tex]H_o : \mu = x[/tex]

Here [tex]\mu[/tex] is the mean and  x  is the value  

 the possible values of the  alternative hypothesis is  [tex]\mu > x \ \ or \ \ \mu < x[/tex]

Now from the value given we see that the  [tex]p-value > \alpha[/tex]  hence

The decision rule is  

    Fail to reject  the null hypothesis

Answer:

The answer is C

Step-by-step explanation:

Use the formula a I = P + r x t

Which means Interest equals Price plus Rate times Time.

So the formula is 600 x 0.08 x 45 ÷ 360.

The answer is $6.00

Answer:

Statistics.

Step-by-step explanation:

Statistics is the branch of exact sciences that has the objective of collecting data from reality from taking samples of a specific group of society or a particular situation, thing or event, and comparing the differences between these samples to obtain a general sample of a certain common characteristic.

Thus, statistics seeks through comparison to establish parameters on which the other sciences are based in order to develop theories, relying on the repetition of characteristics common to the groups analyzed.

Your answer will be C

Answer:

Step-by-step explanation:

Given the expression;

3/5 * 2/7

We are to find the product of bothh fractions

3/5 * 2/7

= (3*2)/(5*7)

= 6/35

Hence the correct result is 6/35 or StartFraction 6 Over 35 EndFraction

Answer:

A

Step-by-step explanation:

Answer:5.25

Step-by-step explanation:

3(1/7 + 1/x) = 1

3([x + 7]/7x) = 1

3x + 21 = 7x

4x = 21

x = 21/4 OR 5.25

It will take wendy 5.25hrs to clean the house by herself.

In order to get the time it take wendy to clean the house by herself, we will use the expression:

1/a = 1/x + 1/y

1/3 = 1/7 + 1/y

1/y = 1/3 - 1/7

1/y = 7-3/21

1/y = 4/21

y =  21/4

y =  5.25hrs

Hence it will take wendy 5.25hrs to clean the house by herself.

Step-by-step explanation:

6x+12 = 9x-3

3x = 15

x= 5

Answer:

x < 25

Step-by-step explanation:

x/2.5 < 10

you need to get x alone so you multiply both sides by 2.5 to get the 2.5 crossed out on one side

x < 2.5 times 10

Answer:

g=9.4

Step-by-step explanation:

subtract 1.5 from both sides

The Z-score for a weekly rental is 2.45 which is the correct answer would be option (B).

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

Given the average cost to rent a car for a week is $276

And the standard deviation is $60

To determine the Z-score for a weekly rental of $423.00

Here,

ц = 276

σ = 60

X = 423

⇒ z-score = (X-ц )/σ

Substitute the values,

⇒ z-score =  (423 - 276)/60

⇒ z-score = 147/60

⇒ z-score = 2.45

Hence, the z-score for a weekly rental is 2.45.
