Answer:
The P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is 0.793 which is high so there is not sufficient evidence to conclude that there is a linear correlation between brain volume and IQ score in males.
Step-by-step explanation:
We are given the following information in the question:
p-value = 0.793
Significance level = 0.05
Since p value is greater than the significance value so we fail to reject the null hypothesis and accept the null hypothesis. We conclude that there is not a significant linear relationship between two variables.
Thus, we can write:
The P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is 0.793 which is high so there is not sufficient evidence to conclude that there is a linear correlation between brain volume and IQ score in males.
There are 150 teachers because 20 * 150 is 3000.
Answer:
4x 32x + 1 = 28x + 1
Step-by-step explanation:
4x-32x+1
=-28x+1

Answer:
- no square roots: -1000, -8
- one square root: 0
- two square roots: 8, 64, 1000
- no cube roots: <none>
- one cube root: -1000, -8, 0, 8, 64, 1000
- two cube roots: <none>
Step-by-step explanation:
The attached graph shows the square root relation (red) and the cube root function (blue). The function values are shown for x=0 and x=±8.
You can see that there are 2 square roots for positive numbers, one square root for 0, and 0 square roots for negative numbers. There is exactly 1 cube root for any number.
- no square roots: -1000, -8
- one square root: 0
- two square roots: 8, 64, 1000
- no cube roots: <none>
- one cube root: -1000, -8, 0, 8, 64, 1000
- two cube roots: <none>

<em>Additional comment</em>
We call the square root curve a "relation" because it is <em>not a function</em>. A relation that is a function will have only one y-value for each x-value. For positive x-values, there are two square roots.
Judy spent 55 mins at gym.
Step-by-step explanation:
Let the time spent by Judy be 'J'
Let the time spent by Sandy be 's'
Mary spent 3 hours at gym.
Sandy spent 50 mins less than Mary
S = 3hours - 50 mins
S = 2 hours 10 mins
Judy spent 1 hour 15 mins less than Sandy.
J = S - 1hour 15 mins
J = 2 hours 10 mins - 1 hour 15 mins
J = 55 mins
Judy spent 55 mins at gym.
