Answer:
-11.
Step-by-step explanation:
f(x) = √(3 - 2x), x ≤ 3/2
let y = √(3 - 2x)
y^2 = 3 - 2x
2x = 3 - y^2
x = (3 - y^2)/2
So f-1(x) = (3 - x^2)/2
f-1(x) = (3 - 5^2) / 2 = -11.

Answer:
base = 3 units
height = 5 units
area = 1/2 x 3 x 5 = 7.5 square units
Answer:
[tex]b[/tex] = 3 units
[tex]h[/tex] = 5 units
[tex]a[/tex] = 7.5 units
Step-by-step explanation:
We can find the base of the figure by counting the number of units from the left to the right of the triangle. So, we can find that the base is 3 units.
The height of the figure can be found by counting how many units the figure measures from the tip to the bottom. The height, then, is 5 units.
The easiest way to find the area of a right triangle is to imagine it as a rectangle, with the same [tex]l[/tex] (length) and [tex]w[/tex] (width) dimensions, and then divide the area of the rectangle by two.
So, to find the area of this rectangle, multiply the length and width, 3 and 5, together.
3 · 5 = 15
Then, we can divide this product by two.
[tex]\frac{15}{2}[/tex] = 7.5
The area is 7.5 units².

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 6.5 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 26 engines and the mean pressure was 6.6 pounds/square inch with a standard deviation of 1.0. A level of significance of 0.01 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Answers
Answer:
The calculated value t = 0.510 < 2.7874 at 0.01 level of significance
The null hypothesis is accepted at 0.01 level of significance
The engineer designed the valve such that it would produce a mean pressure of 6.5 pounds/square inch
Step-by-step explanation:
Step:-1
Given that mean of the population (μ) = 6.5 pounds/ square inch
Given that the sample size 'n' = 26
Given that mean of the sample ( x⁻) = 6.6 pounds/ square inch
Given that the standard deviation of the sample (σ) = 1.0
t₀.₀₁ = 2.7874
Step:-2
Null hypothesis:H₀: μ = 6.5
Alternative Hypothesis:H₁: μ ≠6.5
Test statistic
[tex]t = \frac{x^{-}-mean }{\frac{S}{\sqrt{n} } }[/tex]
[tex]t = \frac{6.6-6.5}{\frac{1.0}{\sqrt{26} } }[/tex]
t = 0.510
The calculated value t = 0.510 < 2.7874 at 0.01 level of significance
Final answer:-
The calculated value t = 0.510 < 2.7874 at 0.01 level of significance
The null hypothesis is accepted at 0.01 level of significance
The engineer designed the valve such that it would produce a mean pressure of 6.5 pounds/square inch

you would cross multiply meaning 6(2x+2)=11(x-4) Then you distribute 6 so it would be 12x+12=11x-44 then you have to move the constant and the variable so 12x-11x= -44-12 so then the answer would be x = -56

A bowl is in the shape of a hemisphere. The radius of the bowl is 10 centimeters. How many liters of water can the bowl hold?
(1,000 cm = 1 liter)
Answers
Answer:
The bowl can hold 2.094 L.
Step-by-step explanation:
We want to find the volume of the hemisphere to calculate how many liters the bowl can hold. To find the volume of a hemisphere, we use this equation:
V = (2/3)•(π)•(r)³
Let's plug in what we know.
V = (2/3)(π)(10)³
Evaluate the exponent.
V = (2/3)(π)(1000)
Multiply.
V = 666.667π
V = 2094.395 cm³
Remember that 1000 cm = 1 liter, and we want to know how many liters the bowl can hold.
= 2094.395/1000
= 2.094 L
The bowl can hold 2.094 L.
Hope this helps!

Select How many numbers are 10 units from 0 on the number line?
Answers
Answer:
2 numbers are 10 units from 0
Step-by-step explanation:
2 numbers are 10 units from 0. If you start from zero and count 10 units to the right, you should be at a positive number. But, you can also move 10 units to the left. If you do this, you should be at a negative number that is ALSO 10 units away from 0, just in a different direction than positive number. both are 10 units from 0. There always 2 numbers, one 10 units to the right of zero, and one 10 units to the left of zero. Hope this helped! Tell me if I'm wrong or right.
Answer: 2 numbers
Step-by-step explanation:
I'm assuming you are talking about a normal number line and if so, you can count 10 units up and down.
When you do that, you find -10 and 10 which are two numbers so the answer would be 2 numbers
This is assuming that you are talking about a normal number line
