Answer:
it is. opiton A : 4.8
Step-by-step explanation:
since the side l to m is 4. in and it is mulipied by three to get the new side l' to m' whixh is 12 in. then we multiply 8 by 3 which is 24 and now we look for what times 5 is 24
and that is 4.8
Answer:
35 = a
Step-by-step explanation:
using the law of logarithms
• 
x = n ⇔ x = 
= 35 ⇒ 35 = a
Answer:
One sqrt(7)*x -49sqrt(x)
Two -30sqrt(2)a
Right: - 3 cuberoot(2a)
Step-by-step explanation:
Left Questions
One
sqrt(7)x ((sqrt(x) - 7sqrt(7) ) Remove the Brackets
- sqrt(7x) * sqrt(x) - sqrt(7x) * 7sqrt(7)
- √(7*x)*sqrt(x) - 7*7*sqrt(x) Combine
- √7 (x) - 49x
This question has a a slight bit of ambiguity in it. Is the x outside the brackets underneath the root sign or not? I have taken it as not. Leave a note if I am wrong. <em><u>Edit</u></em>: This question clears itself when you use the original statement. I think it is correctly represented now. When you use √ you have to use brackets to show what is under the root sign.
Two
You can take a lot of common factors out side the brackets.
The common factors are 3*sqrt(2)*a When you do that, you are left with
- 3*sqrt(2)*a * ( 11 - 21)
- 3*sqrt(2)*a * (-10)
- The final answer is
- -30sqrt(2)*a
Of course there are other, more direct ways of doing this.
Right Question.
The problem here is answering in such a way that you are showing work.
Let z = 3∛(2a)
The problem now becomes
z*(1 - 2)
- z
Now substitute back
-3∛(2a) Answer
Answer:
Option D)
The area below the standardized test score is 0.8413
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 85
Standard Deviation, σ = 5
We are given that the distribution of score is a bell shaped distribution that is a normal distribution.
Formula:
P(score is below 90)
Calculation the value from standard normal z table, we have,
Thus, the correct answer is
Option D)
The area below the standardized test score is 0.8413
