Which radical expression is equivalent to c^1/2
Answer:
it would be √c
Step-by-step explanation:
when you have fractional exponets, the denominator becomes the radical that you want to find so in this case since its 2 it would be he nomal √ (remeber that when you have a √ with no numbers. it automatically indciates that there is a two) , the numerator of the fraction is the exponent of the number that is inside the radical so in reality it would be √c^1 but we don't write the exponent 1 so it would be √c

What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Chandler is three more than 5 times as many years old as his sister Kayla. In 9 years he will be twice as old as she will be.
Then the equation will be
C = 3 + 5K ...1
C + 9 = 2(K + 9) ...2
From equations 1 and 2, we have
3 + 5K + 9 = 2(K + 9)
5K - 2K = 18 - 12
K = 2
The Chandler's age will be
C = 3 + 5K
C = 3 + 5 x 2
C = 13
Now Chandler's age will be 22 now. Then the correct option is E.

In the state of New Mexico, 85% of the land is above 4,000 feet in elevation.
Which fraction is equivalent to 85%?
A 4
5
B
100
17
20
1
85
Answer: 17/20
==============================
Work Shown:
x% = x/100
85% = 85/100
85% = (17*5)/(20*5)
85% = 17/20
------------
You could also go through all the answer choices to see what works and what doesn't.
For instance, 4/5 = 0.80 = 80%, so that is a non-answer.
But 17/20 = 0.85 = 85% which is the answer.

Consider the hospital from problem 4 of the homework that is using a statistical test to decide whether or not to accept future shipments of syringes from a supplier. The two errors the can make are to reject shipments that are actually acceptable and to accept shipments that do not meet the requirements. The hospital has decided that the error of accepting shipments that do not meet the requirements is substantially more important. They would like to ensure that they do not make this error even if that means increasing the chance that they reject acceptable shipments. When selecting their alpha (choosing between 0.01, 0.05 and 0.10) which alpha level provides the highest protection against this type of error?
a) alpha-0.01
b) alpha-o.05
c) alpha-0.10
Answer:
The correct option is a
Step-by-step explanation:
Gnerally assuming that
The null hypothesis is that the syringes from a supplier does not meet the requirement
and
The alternative hypothesis is that the syringes from a supplier meets the requirement
Now in order not to commit type I error which is wrongfully rejecting the null hypothesis then the level of significance need to be lower than the p-value (this is obtained from the z-table for any given z-score ) hence the suitable level of significance to achieve the hospitals aim is alpha-0.01

PLEASE HELP IM TIMES AND EXPLAIN STEP BY STEP , so using substitution method solve the system of equations , y = 2x + 8 and y = 4x - 2 , whoever answers step by step gets brainliest
Answer:
y= 2x + 8 , y = 4x - 2
2x + 8 = 4x - 2
8 = 2x - 2
10 = 2x
5 = x
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
y = 2x + 8
substitute the y in the other expression with this expression (you can do it vise versa too but i chose this because it was first)
2x + 8 = 4x - 2
goal is to isolate the variable
add 2 to both sides (this cancels out the -2 on the right side)
2x + 8 + 2 = 4x - 2 + 2
2x + 10 = 4x + 0
2x + 10 = 4x
subtract -2x from both sides (cancels out the 2x on the left side)
2x - 2x + 10 = 4x - 2x
0x + 10 = 2x
10 = 2x
divide both sides by 2 (cancels out the 2 on the right side)
10 ÷ 2 = 2x ÷ 2
5 = 1x
5 = x
variable is isolated and tells us that x = 5
