Answer:

-3

Step-by-step explanation:

we khow that the vertex form of a function is written this way :

f(x)=a(x-h)²+k

  • the coordinates of the vertex are (h,k) so from the graph we can deduce that k = -3

Answer:

We do not reject the Null Hypothesis

Step-by-step explanation:

From the question we are told that:

Sample size n=23

Population mean \mu=9.02cm^3

Sample mean \=x=8.16

Standard deviation \sigma=0.7cm^3

Significance level \alpha =0.01

Generally the Null and and alternative Hypothesis are as follows

 H_0:\mu=9.02cm^3

 H_a:\mu

Therefore t critical Value is

 t\ critical\ Value=(\alpha,df)

 t\ critical\ Value=(0.01,22)

Where

  df=n-1\\\\df=23-1=>22

Therefore

From t Table

 t value=-2.8

Generally the equation for Z Critical is mathematically given by

 t=\frac{\=x-\mu}{\frac{\sigma}{\sqrt{n} } }

 t=\frac{8.16-9.02}{\frac{0.7}{\sqrt{23} } }

 t=-5.89

Therefore

Since the t test statistics is greater than the Critical value

Hence,we do not reject the Null Hypothesis

What is the answer to 2 + (c + 0) = ?
ipn [44]
C=-2 because you would transfer to the other side making it negative. It can't be a negative so you divide -1 to 2. Making it -2.

The y-intercept of the line whose equation is x - y = 7 is A.) 7 B.) 1 C.) -7
enyata [817]
C) -7

Explanation: If you rearrange the equation into slope-intercept form, you get y = x - 7 so -7 is the b value (y intercept)
