Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with μ=101 and σ=24. (a) what proportion of children aged 13 to 15 years old have scores on this test above 83 ? (note: please enter your answer in decimal form. for example, 45.23% should be entered as 0.4523.)
Answers
Answer:
a) 0.7734
Step-by-step explanation:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 101, \sigma = 24[/tex]
(a) what proportion of children aged 13 to 15 years old have scores on this test above 83 ?
This is 1 subtracted by the pvalue of Z when X = 83. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{83 - 101}{24}[/tex]
[tex]Z = -0.75[/tex]
[tex]Z = -0.75[/tex] has a pvalue of 0.2266
1 - 0.2266 = 0.7734
The answer is 0.7734

Step-by-step explanation:

y = – 3sin(2x) - 5
a. Amplitude = -3, Midline = -5
b. Amplitude = 3, Midline 5
c. Amplitude = 3, Midline - 5
d. Amplitude = 2, Midline = – 3
O a.
Answers
Step-by-step explanation:
Amplitude of the sine function is 1.
So if its multiplied by -3, its amplitude is 3 (its always positive).
The midline of sin x is 0.
The midline of sin 2x is also 0.
The midline of -3*sin 2x is also 0.
So if you subtract this function by 5, then the new midline is -5.

A function assigns the value of each element of one set to the other specific element of another set. The interval for which the given function is increasing is (-2,0).
What is a Function?
A function assigns the value of each element of one set to the other specific element of another set.
A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.
The given function is increasing only when the slope of the function is positive and when the value of x is increased from -2 to 0. Therefore, it can be concluded that the interval for which the given function is increasing is (-2,0).

The bill at a restaurant is $160. You leave a 20% tip. What is your total restaurant bill, including the tip? 20 points!
Answers
Answer:
$192
Step-by-step explanation:
Bill: $160.00
Tip: 20%
To figure out 10%, you need to move the decimal point over to the left one place: $16.00
10%: $16.00
16 times 2= $32.00
160.00+32.00= $192.00
160 20% =32
160+32= 192

Find the sum of the first 22 terms of the arithmetic sequence, the first term is - 2 and the common difference is -5.
Answers
Answer:
The sum of the first 22 terms of the sequence is -1199.
Step-by-step explanation:
Arithmetic sequence:
The general term of a arithmetic sequence is given by:
[tex]A_n = a_1 + (n-1)r[/tex]
In which [tex]a_1[/tex] is the first term and r is the common difference.
The sum of the first n terms of a arithmetic sequence is given by:
[tex]S_n = \frac{n(a_1+a_n)}{2}[/tex]
First term is - 2 and the common difference is -5.
This means that [tex]a_1 = -2, a_n = -5[/tex]
Sum of the first 22 terms
[tex]S_{22} = \frac{22(-2+a_{22})}{2} = 11(-2+a_{22})[/tex]
In which
[tex]a_{22} = -2 + (22-1)(-5) = -107[/tex]
So
[tex]S_{22} = 11(-2 - 107) = 11(-109) = -1199[/tex]
The sum of the first 22 terms of the sequence is -1199.

1. If 5x + 6 = 10, what is the value of 10x + 3?
Answers
All because, we only need to find the value of x.
We are given two equations.
5x + 6 = 10 and 10x + 3 =?
So, we will find the the value of x in the first equation, so that we can substitute the value of x in the second one and there we are with the answer.
5x + 6 = 10
For finding the value of x, all we have to do is,
Transpose the number 6 to 10
Therefore. 5x = 10 - 6 ( Take the equal sign as The Magic Bridge on which if anyone crosses it , will change its sign.)
So we have,
5x = 4
So x = 4/5 ( Multiplication will change to division after crossing the equal sign)
( Doubtful? Substitute the value of x and try!)
Now that we got the value of x,
We can just simply substitute the value of x in the second equation.
10x + 3 = ?
x = 4/5
10*4/5 +3 => 5 and 10 get canceled to 2 at the numerator.
By normal multiplication and then addition, we will get,
8 + 3 = 11

An account earns annual simple interest. Find the balance of the account.
$5,000 at 6% for 9 months.
Answers
Answer:
$7700
Step-by-step explanation:
As the account earns 6% interest, if we find 6% of $5000 we get $300, the interest is simple and given every month, meaning you get $2700 in interest as $300 x 9 months = $2700
$5000 initial + $2700 interest = $7700
EDIT:
It could be that the interest is 6% yearly, which means that yearly you get 6% interest, and the answer is $5225.
6% interest is $300 per year
$300÷12= $25 per month
$25 x 9 months = $225
$5000 initial plus $225 interest = $5225 total
