♥ The X is meaning to times this equation.
♥ Time/Multiply.
♥ You can see this as • x or * when doing multiplication.
♥ Therefore if we solve:
♥ 80*34 we get
♥ 2720
Answer:
1/4x4=1
1/20x4=4/20 or 1/5 which means he can run 5 mile an hour.

Answer:
(D) No, the answer is not reasonable. It should be about 10 pounds.
Step-by-step explanation:
Hotdog = 4 2/5 pounds
Hamburger = 3 1/2 pounds
Chicken = 2 3/10 pounds
Total
= 4 2/5 + 3 1/2 + 2 3/10
= 4 4/10 + 3 5/10 + 2 3/10
= 9 12/10
= 10 2/10
= 10 1/5
Answer:
No the evidence is not sufficient
Step-by-step explanation:
From the question we are told that
The sample size is
The sample proportion is
The population proportion is
The Null hypothesis is
The Alternative hypothesis is
The level of significance is given as
The critical value for the level of significance is
Now the test statistic is mathematically evaluated as
substituting values
Since the critical value is greater than the test statistics then the Null hypothesis is rejected which there is no sufficient evidence to support the claim
Answer:
see explanation
Step-by-step explanation:
given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex which is also the axis of symmetry is
= -
y = 3x² - 24x + 38 is in standard form
with a = 3, b = - 24 and c = 38, hence
= - = 4
Substitute x = 4 into the equation for corresponding y- coordinate
y = 3(4)² - 24(4) + 38 = 48 - 96 + 38 = - 10
vertex = (4, - 10)
equation of axis of symmetry is x = 4
