Answer:
6 bananas, 24 bapples.
Step-by-step explanation:
If Omar has 4 times as many apples as bananas: then if a is the number of apples and b is the number of bananas, then:
Let's say there are b bananas
Therefore there must be 4b apples
In total that gives 5b fruit.
Therefore since there are 30 fruit in all:
5b = 30
Therefore, b = 6
And since there are 30 fruit overall, 30 - 6 = 24
So there 24 apples overall and 6 bananas.
Answer:
The 9th percentile is 40.52.
Step-by-step explanation:
We are given that the random variable X is normally distributed with a mean of 50 and a standard deviation of 7.
Let X = <u><em>the random variable</em></u>
The z-score probability distribution for the normal distribution is given by;
Z = 
~ N(0,1)
where, 
= population mean = 50
= standard deviation = 7
So, X ~ Normal(
)
<u></u>
<u>Now, the 9th percentile is calculated as;</u>
P(X < x) = 0.09 {where x is the required value}
P( < 
) = 0.09
P(Z < ) = 0.09
Now, in the z table the critical value of x that represents the below 9% of the area is given as -1.3543, i.e;
x = 40.52
Hence, the 9th percentile is 40.52.

Comment
The answer to this depends on what you have been told. I don't want to go into a whole lot of talking when you don't need it.
It also depends where C is (in what quadrant). If it is just an ordinary triangle, not drawn in a coordinate system, then the answer will be plus.
Step One
To made things simple, draw ABC with BC on the horizontal.
Label the left acute angle as C and the other end of the hypotenuse as A.
Step Two
Label the hypotenuse as having a length of 1 which means that x is less than 1.
Step 3
Label len BC as x. You should have AC = 1 and AB = x
Step 4
Find CB
Use the pythagorean theorem to find CB.
a^2 + b^2 = c^2
c = 1
b = AB = x
a = ??
a^2 + x^2 = 1^1 Subtract x^2 from both sides.
a^2 = 1 - x^2 Take the square root of both sides.
sqrt(a^2) = sqrt(1 - x^2)
a = sqrt(1 - x^2)
Answer
sin(A) = sqrt(1 - x^2)/1
Comment.
Any length can be given to the hypotenuse. Suppose it is y = z*x . Then AB can be reduced to x by dividing all sides by z.
Using a much simpler example suppose you are given a right triangle of 6 8 and 10. To reduce the hypotenuse to 1 you would divide by 10. to give you 0.6 0.8 and 1. That would not change the value of sin(C) and in that case you would call x = 0.8 or x = 0.6 depending on how you drew the triangle.
I'm sorry, this got very long because I had to get it correct.
The key step is getting sqrt(1 - x^2)
If this is giving you a royal headache, please PM me and I'll try and say another way.
Cost of 25 pound flour is $30.75.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Price of 3 pound flour = $3.69
She needs 25 pounds of flour to make enough cookies for a bake sale.
Now, Price of 3 pound flour = $3.69
Hence, Cost of 1 pound flour = $3.69 ÷ 3 = $1.23
So, Cost of 25 pound flour = 25 x $1.23
= $30.75
Therefore, Cost of 25 pound flour is $30.75.
