Answer:
A. 50%; This percentage is lower than expected in a normal distribution
Answer:
A) 50%; This percentage is lower than expected in a normal distribution.
Step-by-step explanation:
Data points given:
55, 54, 66, 38, 53, 56, 57, 66, 45, 65
n = 10
The mean for the data points:
[tex] \frac{55+54+66+38+53+56+57+66+45+65}{10} [/tex]
Mean = 55.5
Standard deviation of data points:
[tex] = \sqrt{\frac{55-55.5)^2+(54-55.5)^2+(66+55.5)^2+(38-55.5)^2+(53-55.5)^2+(56-55.5)^2+(57-55.5)^2+(66-55.5)^2+(45-55)^2+(65-55)^2}{10}} [/tex]
= 8.59
Now let's find the data points that lie between 64.09 i.e (55.5 + 8.59) and 46.91 i.e (55.5-8.59)
We can see that 5 data points lie between 64.09 and 46.91 which are { 55,54,53,56,57}
The correct option is A, which states that 50% percentage is lowee than expected.
Carlos writes 1/8 of a page in 1/2 of a minute. How many pages will he have written in one minute?
Answer:
1/4 pages
Step-by-step explanation:
1/8 page in 1/2 minutes
X number of pages in 1 minute
Answer:
2/8
Step-by-step explanation:
Since 1/2 a minute is 1/8 of a page. One full minute would mean another 1/2, so that means we need another 1/8, and 1/8 + 1/8= 2/8
what pairs of numbers that would satisfy the statement:the sum of 2 numbees is 18
There is an infinite number of such pairs. Even if you consider just the integers, there is still an infinite number of pairs. If you limit the number in the pairs to whole numbers, then here are the pairs:
0, 18
1, 17
2, 16
3, 15
4, 14
5, 13
6, 12
7, 11
8, 10

General conic equation
There are 3 types of conics: parabola, ellipse, and hyperbola.
Equation of a parabola: y = a(x - h)² + k or x = a(y - k)² + h
Equation of an ellipse: [tex]\frac{(x-h)^{2}}{a} +\frac{(y-k)^{2}}{b} =1[/tex]
Equation of a hyperbola: [tex]\frac{(x-h)^{2}}{a} -\frac{(y-k)^{2}}{b} =1[/tex]
The general equation for all of them is:
Ax² + Bxy + Cy² + Dx + Ey + F = 0 ; A, B, C, D, E, F ∈ Integers

Alan has an annual base salary of $24,000. In addition to his salary, he earns 8% of his total sales (S). If he wants to earn at least $56,000 next year, how much does he need to sell?
A. S > $244,480
B. S > $550,000
C. S > $448,000
D. S > $400,000
Answer:
D. S > $400,000
Step-by-step explanation:
His salary is base salary plus commission
salary = 24000 + .08 sales
He wants a salary of at least 56000
56000<= 24000 +.08 sales
Subtract 24000
56000-24000<= 24000-24000+.08*sales
32000<= .08 * sales
Divide each side by .08
32000/.08 <= .08/.08 * sales
400000<= sales

Beanbag chairs it normally sell for $36.30 on sale for $32.12 find the percent of discount
Answer:
Step-by-step explanation:
Suppose a+b=2a. Which one of these expressions equals b−a? Choose 1 answer: 1) 2B 2) 2A 3) A-B 4) -2B 5) -B SQUARED
The expression for [tex]\(b - a\) is \(0\)[/tex].
To find the expression for [tex]\(b - a\)[/tex], we can use the given equation [tex]\(a + b = 2a\)[/tex] and solve for [tex]\(b\).[/tex]
Starting with [tex]\(a + b = 2a\)[/tex], we can subtract [tex]\(a\)[/tex] from both sides to isolate [tex]\(b\):[/tex]
[tex]\[b = 2a - a\][/tex]
[tex]\[b = a\][/tex]
Now, we can substitute [tex]\(b = a\)[/tex] into the expression [tex]\(b - a\):[/tex]
b - a = a - a
b - a = 0
Therefore, the expression for [tex]\(b - a\) is \(0\)[/tex].

74.362 to the nearest tenth
Answer:
73.4
Step-by-step explanation:
When they ask for the nearest tenth you check the hundreth, it its 5 or ore than you increase the tenth
The number 74.362 would round down to 74.4
For Rounding some number to a specific value is making its value simpler mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of trimmed from the right in terms of exact digits.
We need to round 74.362 to the nearest tenth,
To round 74.362 to the nearest tenth, we need to look at the digit in the hundredth place, which is 2. Since 2 is less than 5, we round down and keep 4.
Therefore, rounding 74.362 to the nearest tenth gives us 74.4.

The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00. Write a function to represent this scenario.
Which graph represents this wage increase for x < 12?

Answer:
1st=300,000 2nd=50
Step-by-step explanation:
What is the remainder when the polynomial f(x)=3x^3-4x^2+2x+8 is divided by (x-5)
The remainder when the polynomial f(x) = 3x³ - 4x² + 2x + 8 is divided by (x - 5) is constant an equal f(5).
Substitute x = 5 to the polynomial:
[tex]f(5)=3(5^3)-4(5^2)+2(5)+8=3(125)-4(25)+10+8\\\\=375-100+18=275+18=293[/tex]
Answer: (3x³ - 4x² + 2x + 8) : (x - 5) = q(x) + 293.
Can someone explain this please ? Like explain how to do it
Answer:
-2
Step-by-step explanation:
First, you have to find the slope.
Rise 1
------- = ------ = 1
Run 1
So, the slope is 1.
Next, if you write the graph in the slope intercept from, then it will be,
y=mx+b
y=1x+-3
We already know that x is 1 So,
y=1(1)+-3
y=-2
So, the answer is -2! Hope this helps!!!
Answer:
When x = 1 , y = -2.
Step-by-step explanation:
I'm assuming you want the equation of this line.
The 2 points close together are (0, -3) and (-1, -4).
Slope = (y1-y2) / (x1 -x2)
= (-4-(-3)) / (-1 - 0)
= -1 / -1 = 1
The y-intercept is where y = -3.
The equation of a straight line is y = mx + c where m = the slope and c = the y-intercept, so the equation of this line is y = 1x - 3
or y = x - 3 (the 1 may be omitted).
When x = 1, y = 1 - 3 = -2 (answer)

$41 14.6 (approx)
Discussion:
# 39
From plane trigonometry
cos(69) = x/17 or
x = 17 * cos(69) = 6.1 (approx)
#41
sin(59) = x/17 or
x = 17 * sin(59) = 14.6 (approx)

You spent z dollars today. Today, you spent 5.5 times as many dollars as you spent yesterday. Which expression correctly shows how much you spent yesterday?

5.5z

5.5 ÷ z

5.5(1 − z)

z ÷ 5.5

none of the above
Answer:
Z ÷ 5.5
Step-by-step explanation:
The correct expression to show how much was spent yesterday when z dollars were spent today and that amount is 5.5 * the spending of yesterday is z divided by 5.5. The correct answer is option (D) z ÷ 5.5.
If you spent z dollars today and that amount is 5.5 * what you spent yesterday, to find out how much you spent yesterday, you would divide the amount spent today by 5.5. This is because the relationship between what was spent today (z dollars) and what was spent yesterday is multiplicative. Today’s spending (z) is equal to 5.5 * yesterday’s spending, so to find out what you spent yesterday, you would express it as z divided by 5.5.
Thus, the correct answer to the student's question is option (D) z ÷ 5.5.
parallelogram JSTP∼parallelogram BFMY
Drag the answers into the boxes to match each part of parallelogram JSTP with the corresponding part of parallelogram BFMY .

[tex]\angle P=\angle Y;[/tex]
[tex]\overline {ST}[/tex] and [tex]\overline {FM};[/tex]
[tex]\angle T=\angle M;[/tex]
[tex]\overline {JP}[/tex] and [tex]\overline {BY}.[/tex]
Step-by-step explanation:
Similar figures have proportional corresponding sides and congruent corresponding angles. If parallelogram JSTP is similar to parallelogram BFMY, then
[tex]\angle J=\angle B;[/tex] [tex]\angle S=\angle F;[/tex][tex]\angle T=\angle M;[/tex][tex]\angle P=\angle Y;[/tex][tex]\dfrac{JS}{BF}=\dfrac{ST}{FM}=\dfrac{TP}{MY}=\dfrac{JT}{BM}=\dfrac{JP}{BY}=\dfrac{SP}{FY}.[/tex]Answer:
Step-by-step explanation:
p=y
by looking at the end of the angles you can tell that P is corresponding to y
ST=FM
since both are in the middle of their angles they are both considered a corresponding
T=M
both are the third within their angle there for corresponding
JP=BY
both are within the same place with therefore equal
