Let g(x) = 2x2 - 11x. Find g(-1).

1 answer:

6 0

Hey there :)

g ( x ) = 2x² - 11x

For g ( - 1 ) , you need to substitute - 1 in place of x

g ( - 1 ) = 2 ( - 1 )² - 11 ( - 1 )
= 2 ( 1 ) + 11
= 2 + 11
= 13 → Your answer

$4 is what percent of $50 ?

dmitriy555 [2]

Answer

Find out the $4 is what percent of $50 .

To prove

By using the percentage formula

$Percentage = \frac{Part\ value\times100}{Total\ value}$

As given in the question

Part value = $4

Total value = $50

Put all the values in the percentage formula as mentioned above.

$Percentage = \frac{4\times100}{50}$

solving the above

$Percentage = \frac{400}{50}$

Percentage = 8%

Therefore $4 is 8% of $50 .

Sergeu [11.5K]

Answer:

Check the explanation

Step-by-step explanation:

Below are the null and alternative Hypothesis,

Null Hypothesis, H0: μ = 300000

Alternative Hypothesis, Ha: μ < 300000

Test statistic,

z = (xbar - mu)/(sigma/sqrt(n))

z = (288000 - 300000)/(80000/sqrt(25))

z = -0.75

P-value Approach

P-value = 0.2266

As P-value >= 0.05, fail to reject null hypothesis.
