The graph of the parabola is now vertically translating by 3 units up

Answer:

2 units right

3 units up

Step-by-step explanation:

the graph y=(x+2)² is the parent function y=x^2 translated 2 units left

the graph y=x²+3 is the parent function y=x^2 translated 3 units up

so, the translation from y=(x+2)² to y=x²+3 is:

2 units right (to get to zero)

3 units up

(you can change the order if you want, it doesn't really matter here)

For a left-tailed test, the critical value of z so that a hypothesis test would reject the null hypothesis at 1% significance le

mars1129 [50]

Answer:

C.-2.33

Step-by-step explanation:

We are given that

Significance level, $\alpha =1$ %=0.01

We have to find the critical value of z for a left-tailed test.

To find the critical value , we will use the z-table at significance level 0.01 for left-tailed test.

By using the z-table at significance level 0.01 for left-tailed test

The critical value of z at 1% significance level for left-tailed test

=-2.33

We get p-value by using z-critical value

P-value=0.0099<0.01

So, hypothesis test would be reject the null hypothesis at at 1% significance level.

Hence, the critical value of z=-2.33

Option C is true.

GETS BRAINILIST!!!A class has 6 boys and 14 girls. What is the ratio in simplest form that compares number of boys to total numb

FinnZ [79.3K]

Answer:

3:10

Step-by-step explanation:

1. Find the total number of students by doing

14 + 6= 20

2. Now make your ratio

6:20

3. To make it in simplest form, divide both sides by 2

6 divided by 2 is 3

20 divided by 2 is 10

4. Your answer is

3:10

Porphyrin is a pigment in blood protoplasm and other body fluids that is significant in body energy and storage.

ra1l [238]

Answer:

a) 0.923

b) 0.957

c) 0.88

d) 0.077

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 40

Standard Deviation, σ = 14

We are given that the distribution of number of milligrams of porphyritic per deciliter of blood is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(xis less than 60)

P(x < 60)

$P( x < 60) = P( z < \displaystyle\frac{60 - 40}{14}) = P(z < 1.4285)$

Calculation the value from standard normal z table, we have,

$P(x < 60 ) =0.923 = 92.3\%$

b) P(x is greater than 16)

$P(x > 16) = P(z > \displaystyle\frac{16-40}{14}) = P(z > -1.7142)\\\\P( z > -1.7142) = 1 - P(z \leq -1.7142)$

Calculating the value from the standard normal table we have,

$1 - 0.043 = 0.957 = 95.7\%\\P( x > 16) = 95.7\%$

c)P(x is between 16 and 60)

$P(16 \leq x \leq 60) = P(\displaystyle\frac{16 - 40}{14} \leq z \leq \displaystyle\frac{60-40}{14}) = P(-1.7142 \leq z \leq 1.4285)\\\\= P(z \leq 1.4285) - P(z < -1.7142)\\= 0.923 - 0.043= 0.88 = 88%$

$P(16 \leq x \leq 60) = 88\%$

d) P(x is more than 60)

P(x > 60) = 1 - P(x < 60) = 1 - 0.923 = 0.077
