Which of the following is true?
VARVARA [1.3K]

Answer:

The correct option is c which is if this test was one-tailed instead of two-tailed, you would reject the null.

Step-by-step explanation:

a: This statement cannot be true as the p-value for a 1 tailed test is dependent on the level of significance and other features.

b: This statement cannot be true as there is no valid mathematical correlation between the p-value of the one-tailed test and the current p-value.

c: This statement is true because due to the enhanced level of significance, the null hypothesis will not be rejected.

d: This statement is inverse of statement c which cannot be true.

e: The statement cannot be true as there is no correlation between the current p-value and the p-value of 1 tailed test. The correlation exists between the values of one-tailed and two-tailed p-values.

Solve the quadratic function using square root X+10x+25 =18
lawyer [7]

Answer:

= − 7 /1 1  in fraction form

Step-by-step explanation:

STEP 1: Multiply by 1

1 + 1 0 + 2 5 = 1 8

+ 1 0 + 2 5 = 1 8                                                                                                                               STEP 2: Combine like terms

+ 1 0 + 2 5 = 1 8

1 1 + 2 5 = 1 8                                                                                                                       STEP 3: Subtract  2 5   from both sides of the equation

11x+25=18

1 1 + 2 5 − 2 5 = 1 8 − 2 5

STEP 4: Simplify  by subtracting the numbers

1 1 + 2 5 − 2 5 = 1 8 − 2 5

11x+25−25=18−25                                                                                                   1 1 = 1 8 − 2 5                                                                                                                                   1 1 =  -7

STEP 5: Divide both sides of the equation by the same term                                                     1 1 = − 7                                                                                                                         11x/ 11x = −7/ 1 1 (set up as a fraction)                                                                       STEP 6: Cancel terms that are in both the numerator and denominator

=  − 7 /1 1                                                                                                                      SOLUTION

=  − 7 /1 1

A café or for senior citizens a 15% discount off it's regular price of $8.95 for the dinner buffet. What percent of the regular
denis23 [38]

Answer:

Price for Senior Citizen = $7.61

Percent of the regular price = 85% off original

Step-by-step explanation:

Regular Price is $8.95

Seniors get 15% off of that. So, first we need to find 15% of 8.95 and then subtract it from 8.95.

To get percentage of a number, we first convert the percentage to decimal (by dividing by 100) and then multiply it with the number.

15% = 15/100 = 0.15

Fifteen Percent of 8.95 is:

0.15 * 8.95 = $1.3425

Senior Citizen Price = 8.95 - 1.3425 = $7.6075

Rounded to nearest cent = $7.61

How much is this as a percentage of original?

Simple, it is 15% off of the regular price, so this price is 100 - 15 = 85% of original price
