Answer:
0.15%
Step-by-step explanation:
The Empirical Rule ( 68-95-99.7 Rule) states that almost all data falls within 3 standard deviations of the mean for a normal distribution. Under the rule:
68% of the data falls within one standard deviation. 95% percent of the data lies within two standard deviations. 99.7% of data fall within three standard deviationsGiven that:
mean (μ) = 594 and standard deviation σ = 96
68% of the data falls within μ ± σ. That is 594 ± 96. 68% fall within 498 and 69095% percent of the data lies within μ ± 2σ. That is 594 ± 2(96). 95% fall within 402 and 78699.7% percent of the data lies within μ ± 3σ. That is 594 ± 3(96). 99.7% fall within 306 and 882The percentage of people that all fall outside 306 and 882 = 100% - 99.7% = 0.3%. Therefore the percentage of people that are below 306 = 0.3% / 2 = 0.15%
A point is selected at random inside the given figure. What is the probability the point will be in the region labeled B? Enter your answer, as a fraction in simplest form, in the box. The figure is a rectangle that is made up of three rectangles and one square. The rectangles are labeled A, B, and D, and the square is labeled C. Rectangle A is in the upper left portion of the large rectangle. The left side of rectangle A is labeled 5 inches and it is part of the left side of the large rectangle. Rectangle B is in the lower left portion of the large rectangle below rectangle A. The lower side of rectangle B is labeled 3 inches and makes up a part of the lower side of the large rectangle. Rectangle D makes up the right side of the large rectangle and is to the right of rectangle A. The upper side of rectangle D is labeled 3 inches and makes up a part of the upper side of the large rectangle. The right side of rectangle D makes up the entire right side of the large rectangle. Square C lies below rectangle A and between rectangles B and D. The lower side of square C is labeled 4 inches and makes up part of the lower side of the big rectangle. The right side of square C is also labeled 4 inches.
Answer:. 12/90. Or about 13.3%
Step-by-step explanation: If I interpreted your description correctly, and put the dimensions in the correct places, the large rectangle has an overall width of 10 inches and length of 9 inches. The Total Area is 90 sq in.
The rectangle Region B is 3 (given) by 4 (assumed from shared side with the given square) . So the Area of region B is 12 sq in.
The chance of randomly selecting a point is the ratio of the Area of the selected region to the Total Area. In this example, it's 12/90, simplified to 2/15 or about 13.3%

hi ryan
what is the zero of the function below?
f(x)=3x-15
A. -15
B. 0
C. 5
D. 3
Answer:
x = 5 (Answer C)
Step-by-step explanation:
Set f(x) = 3x - 15 = to 0 and solve for x:
3x - 15 = 0
Adding 15 to both sides isolates 3x:
3x = 15
Dividing both sides by 3 yields x = 5 (Answer C)
What is the probability that a blue marble is selected, given that it is large?
Answer:
P(blue given large)=1/2
Step-by-step explanation:
Marble being blue=1/4
Large Marble=2/5
Both blue and large=1/5
2/5x=1/5
x=1/5*5/2
x=1/2
Therefore, 1/2
a bag is filled with 4 red marbles, 3 blue marbles,3 yellow marbles, and 2 green marbles. you randomly choose one marble from the bag. (a) find the number of ways the event can occur. (b) find the favorable outcomes of the event
Answer:
a. 12
b. it depends on the color of the marble.
Step-by-step explanation:
In this case the number of ways would be the number of events, in this case the events would be the total number of marbles since any of them can come out. so:
4 + 3 + 3 + 2 = 12
Therefore, the number of ways the event can occur is 12 ways.
Now, in the favorable outcomes of the event, it would come depending on what color the marble would be, whether it be red, blue, yellow or green.
In each color, the number of the favorable outcomes of the event would be the quantity of each marble, that is, 4 for red, 3 for blue, 3 for yellow and 2 for green.

What is the solution to the equation 5 x = 32?
a. x = 6
b. x = 6.4
c. x = 27
d. x = 160
Answer
x = 32/5 = 6.400
Answer is B
Step-by-step explanation:
1: Rearrange
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
Solving a Single Variable Equation
Solve : 5x-32 = 0
Add 32 to both sides of the equation :
5x = 32
Divide both sides of the equation by 5:
x = 32/5 = 6.400
The correct answer is B.
Answer: x = 32/5 = 6.400
Hope this helps.
Answer:
B
Step-by-step explanation:
5x=32 move the 5 over by dividing
x=5/32. 5 divided by 32 equals 6.4
so x=6.4

Determine which functions have two real number zeros by calculating the discriminant, b2 – 4ac. Check all that apply.
f(x) = x2 + 6x + 8
g(x) = x2 + 4x + 8
h(x) = x2 – 12x + 32
k(x) = x2 + 4x – 1
p(x) = 5x2 + 5x + 4
t(x) = x2 – 2x – 15
Step-by-step explanation:
We need to write the function that have two real number zeros by calculating the discriminant i.e. [tex]b^2-4ac[/tex].
We know that,
If D>0 the roots are real and unequal
If D= 0 roots are real and equal
If D< 0 roots are imaginary or not real and unequal
Function (1)
[tex]f(x)=x^2 + 6x + 8\\\\D=6^2-4\times 1\times 8\\\\D=4[/tex]
D>0 the roots are real and unequal
Function (2)
[tex]g(x)=x^2 + 4x + 8\\\\D=4^2-4\times 1\times 8\\\\D=-16[/tex]
D<0 the roots are real and unequal
Function (3)
[tex]h(x)=x^2 -12x+32\\\\D=(-12)^2-4\times 1\times 32\\\\D=16[/tex]
D>0 the roots are real and unequal
Function (4)
[tex]k(x)=x^2 +4x-1\\\\D=(4)^2-4\times 1\times (-1)\\\\D=20[/tex]
D>0 the roots are real and unequal
Function (5)
[tex]p(x)=5x^2 +5x+4\\\\D=(5)^2-4\times 5\times 4\\\\D=-55[/tex]
D<0 the roots are real and unequal
Function (6)
[tex]t(x)=x^2 -2x-15\\\\D=(-2)^2-4\times 1\times (-15)\\\\D=64[/tex]
D>0 the roots are real and unequal
(1),(3),(4) and (6) have two real number zeroes.

United Steel provides pensions to its employees. An individual pension is 2.3% of the
employee's average salary for the last five years of employment times the number of
years the employee worked for the company. Juan DeMarco worked for 30 years for
United Steel.
The annual salaries he received for his last five years were: $ 93,000, $ 94,000, $ 98,000,
$ 94,000, and $102,000.
What will his annual pension be?
Answer:
$66,378.
Step-by-step explanation:
Average salary for the last 5 years = (93000+94000+98000+94000+102000)
/ 5
= $96,200
So his pension = 96,000 * 0.023 * 30
= $66,378.

Answer:
Step-by-step explanation:
(a) The appropriate formula is C = 2πr. Here r = 14 cm, so
C = 2π)14 cm = 28π cm, or (if we take π to be 22/7), C = 88 cm²
(b) We use the same circumference formula: C = 2πr and solve it for r before inserting numeric values:
C 132 m 7(132 m)
r = -------- and in this case, r = ------------------- = ------------- = 21 m

Suppose an investment of $500 doubles in value every 15 years. How much is the investment worth after 30 years? After 45 years?Write an equation and solve
Answer:
Step-by-step explanation:
well all you have to do is 500 dollars times two, because it times each 15 years right and 30/15=2. So you do $500*2 which is $1000. And you get $1500 in 45 yrs.
So the equations are for each 15 yrs you add 500 dollars to the amount.

In order to use the Pythagorean Theorem, you must know the length or lengths of (all three sides/any 2 sides/any side) of the triangle and know that the measure of one of the angles is (greater than 90°/exactly 90°/less than 90°) .
Answer:
a) Any 2 sides
b) exactly 90°
Step-by-step explanation:
The point of the Pythagorean Theorem is to find the length of the hypotenuse using 2 sides.
This only works for right triangles.
Hope this helps!
-MoCKEry
Answer:
1) any two sides
2)exactly 90 degrees
Step-by-step explanation:
1) The pythagorean theorem only applies to right angle triangles
since right angle triangles measure 90 degrees exactly we will choose exactly 90 as an option.
2) so the formula for pythagorean theorem is a^2+b^2=c^2 where
a=side 1
b= side 2
c=hypotenuse(biggest side)
to find the hypotenuse you need to know both the values of a and b hence we will take the option "any two sides"

Find the mean absolute deviation (MAD) of the data in the pictograph
Answer:
1.5
Step-by-step explanation:
First, find the mean (average) of the data set.
mean = (x1 + x2 + ...)/N
where x1, x2, ... are the data points, and N the total amount of data points.
mean = (7 + 2 + 4 + 3)/4 = 4
Then, mean absolute deviation is computed as follows:
MAD = (|x1 - mean| + |x2 - mean| + ...)/N
MAD = (|7 - 4| + |2 - 4| + |4 - 4| + |3 - 4|)/4
MAD = (3 + 2 + 1)/4 = 1.5
