Answer:
none
Step-by-step explanation:
y = -4x^2 +3x-2
To find the x intercepts, let y =0
0 = -4x^2 +3x-2
Using the discriminant
a=-4, b=3 c=-2
b^2 -4ac
3^2 -4(-4)(-2)
9 -32
-23
Since this is negative all the roots are complex, so it has no real roots
none
First, divide the total pounds of food eaten by 7 (7 days in a week).
2,100/7 = 300 pounds
Then divide this quotient by the 5 hippos.
300/5 = 60 pounds
Therefore, each hippo eats 60 pounds of food every day.
Answer:
3. t-test for the difference between means for two related samples.
Step-by-step explanation:
It is given that a professor of UCI wishes to study what really the students remember from their elementary school days and other such stuffs that were very popular at that time.
therefore the professor put forward two test. In one of the test, he put some question from the elementary school and in other he put one question about a pop culture from that time. He used the same sample for both the tests.
So, since the professor involved the same set of students in his experiment for both the tests, so both the samples are related samples.
Therefore, the test uses is a t - test that is used for the difference between the related samples.
Answer:
To solve the equation, you have to to isolate the variable. So, first you subtract both sides by 7.
x +7 - 7 = -2 - 7
When you simplify further,
x = -9.
Hope this helps! :)
Answer:
2/2
Step-by-step explanation:
the slope is the distance between the two dots. So for the first dot to get to the second dot is up two, and right two
