Answer:
Answer:
A) Total frequency = 30
B) Yes, the distribution is consistent with the label because the frequencies are greatest when the lengths are closest to the labeled size of 1/2 inches which is 0.5 inches.
Step-by-step explanation:
Since the class limit width is 0.010 from the question, we arrive at;
Class Limits Frequency
Length(Inches)
0.470 - 0.479 3
0.480 - 0. 489 5
0.490 - 0.499 9
0.500 - 0.509 12
0.510 - 0.519 1
Following is the frequency distribution table:
How to build a frequency table?The lower limit is given as 3.470 inches.
The upper limit is 3.500 inches.
And the width of each class is 0.010 inches.
Therefore, the intervals will be:
3.470-3.480
3.480-3.490
3.490-3.500

Shelia's measured glucose level one hour after a sugary drink varies according to the normal distribution with μ = 132 mg/dL and σ = 11.3 mg/dL. what is the level L such that there is probability only 0.01 that the mean glucose level of 5 test results falls above L?
Answer:
134.6
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula. This is X when Z has a p-value of 1-0.01 = 0.99. So it is X when Z = 2.325.
The level is L = 134.6
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation, large sample size can be approximated to a normal distribution with a mean and standard deviation

Naomi's fish is 40 millimeters long. Her guinea pig is 25 centimeters long.
How much longer is her guinea pig than her fish?
Explanation 1:
Her guinea pig is
25 cm long.
25 cm = 250 mm
Her fish is 40 mm long, so her guinea pig is longer than her fish by
25 cm − 40 mm = 250 mm − 40 mm = 210 mm= 21 cm
Explanation 2:
First, lets convert the length of Naomi's guinea pig from cm to mm.
1 cm=10 mm
We can multiply each side of the equation by 25 to obtain the length of the guinea pig in mm.
25 × 1 cm = 25 × 10 mm
25 cm = 250 mm
Because we have a length of the guinea pig and the fish in a common metric we can subtract the two values: 250 mm − 40 mm = 210 mm The guinea pig is 210 millimeters longer than the fish. Or, if we want to convert this to centimeters we can divide by 10: 210 millimeters 10 = 21 centimeters

Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.
Step-by-step explanation:
Let a=x+2 and b=x+6
The area of a rectangle is given by
A=a*b
So
[tex](x + 2) \times (x + 6) = {x}^{2} + 8x + 12[/tex]
Answer:
A = x² + 8x + 12
Step-by-step explanation:
Area of a rectangle:
A = bh
A = (x + 6)(x + 2)
A = x² + 2x + 6x + 12
A = x² + 8x + 12

The diameter of a tire is the distance across the tire through the center. Since tires are circular, you can find the circumference of the tire from the diameter. The circumference represents the distance the tire travels when it makes one revolution. If you know the number of inches in a mile and the circumference, you can find the number of times the wheel turns per mile.
First, measure the diameter of the tire in inches.
Secondly, multiply the diameter by pi, which is approximately 3.1416, to find the tire circumference. For example, if the tire has a 20 inch diameter, multiply 20 by 3.1416 to get 62 inches.

Solve the equation: 315= 390- 25q
Answer:
q=3
Step-by-step explanation:
315=390-25q
390-25q=315
390-25q-390=315-390
-25q=-75
Divide both sides by 25
q=3
Answer: q = 3
Step-by-step explanation:
315 = 390 - 25Q
1. Minus 390 from both sides
-75 = =-25q
2. Divde both sides by -25 to get q by itself
3 = q or q = 3

Look at the two quadrilaterals shown below.
Which one of the following statements about these quadrilaterals Is FALSE?
Both quadrilaterals have four equal angles.
Both quadrilaterals have four equal sides.
Both quadrilaterals have opposite parallel sides.
Both quadrilaterals have four right angles. The two shapes are a square and a rectangle
Answer:
"Both quadrilaterals have four equal sides."
Step-by-step explanation:
This statement is only true for a square since as we all know it has four equal sides, but a rectangle has two parallel sides that are equal to each other but on the other two parallel sides, they must differ in length.

"Both quadrilaterals have four equal sides." is the false statement

TIMED HURRY!! For the given equation, find the values of a, b, and c, determine the direction in which the parabola opens, and determine the y-intercept. Decide which table best illustrates these values for the equation: y = x squared + 7 x Table A a b c up or down y-intercept 1 7 0 up (0,0) Table B a b c up or down y-intercept 7 1 0 up (0,0) Table C a b c up or down y-intercept 7 1 0 down (0,0) Table D a b c up or down y-intercept 1 7 0 down (0,0) a. Table A c. Table C b. Table B d. Table D
Answer:
the answer is c
Step-by-step explanation:
We can see that Table A best illustrates the values for the equation.
The answer is (a) Table A.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The given equation is y = x² + 7x.
We can determine the values of a, b, and c by comparing the equation to the standard form of a quadratic equation,
which is y = ax² + bx + c.
In this case,
a = 1, b = 7, and c = 0.
To determine the direction in which the parabola opens, we can look at the coefficient of the x² term, which is a.
Since a is positive, the parabola opens upwards.
The y-intercept is the point where the parabola intersects the y-axis.
To find it, we can set x = 0 in the equation:
y = 0² + 7(0) = 0
So the y-intercept is (0,0).
Thus,
We can see that Table A best illustrates the values for the equation.
The answer is (a) Table A.
