Answer:
0.54035
Step-by-step explanation:
Given that :
Mean, m = 66 inches
Standard deviation, s = 2.5 inches
P(65 < X < 69)
P(X < 69) - P(X < 65)
((69 - 66) / 2.5) - ((65 - 66) / 2.5)
P(Z <(3/ 2.5)) - P(Z <(-1 / 2.5))
P(Z < 1.2) - P(Z < - 0.4)
0.88493 - 0.34458
= 0.54035

Answer:
choice 1) 0, -4/5
Step-by-step explanation:
1/(t² + t) = 1/t - 5
multiply both sides of the equation by (t² + t):
1 = (t² + t)/t - 5t² - 5t
1 = t + 1 - 5t² -5t
-5t² - 4t = 0
t(-5t - 4) = 0
t = 0
-5t = 4
divide both sides by -5:
t = -4/5

Answer:
The constant of proportionality of the equation is 1.5.
Step-by-step explanation:
Equation of proportional measures:
Suppose that y and x are proportional measures. This situation can be equatialized is:
y = ax
In which a is the constant of proportionality.
y = 1.5x. What is the constant of proportionality of the equation?
a = 1.5, so the constant of proportionality of the equation is 1.5.
a certain vehicle can drive 300miles on a tank of 20 gallons. how far can it drive on 30 gallons?
what is the answer in miles ??
PLEASE HELP ME !!!!
Answer:
450 miles
Step-by-step explanation:
First you calculate miles per gallon, which you do by dividing 300/20. This gives us 15. So you can go 14 miles on one gallon.
From there you multiply 15 by 30, since you'll be driving 30 miles. This gives us 450 miles.
Step-by-step explanation:
[tex] \frac{300}{x} \times \frac{20}{30} = \frac{20x}{20} \frac{9000}{20} x = 450miles[/tex]

Step-by-step explanation:
Formula we use:
I = Prt
Given:
P = 7500
r = 5.5% or 0.055
t = 2
Work:
I = Prt
I = 7500(0.055)(2)
I = 412.5(2)
I = 825

What is the sum of 7 of the interior angles of a regular decagon?
Answer:
The answer is 1008 degrees
Step-by-step explanation:
The sum of 7 of the interior angles of a regular decagon is 1008°.
What is interior angle of polygon?It is an angle inside a shape. All the interior angles in a regular polygon are equal.Formula to find the sum of interior angles of a polygon:S = (n - 2) × 180°, where n is the number of sides of the regular polygon.
What is decagon?"It is a polygon having ten sides, ten interior angles and ten vertices."
For given example,
We need to find the sum of 7 of the interior angles of a regular decagon.
Number of sides of decagon (n) = 10
Using the formula of sum of interior angles,
⇒ S = (n - 2) × 180°
⇒ S = (10 - 2) × 180°
⇒ S = 1440°
This means the sum of all interior angles of a regular decagon is 1440°.
We know, there are 10 interior angles of regular decagon.
Let 'x' represents the measure of each interior angle of a regular decagon.
⇒ 10x = 1440°
⇒ x = 1440/10
⇒ x = 144°
This means, the interior angle of a regular decagon measures 144°
So, the sum of 7 of the interior angles would be,
7 × 144° = 1008°
Therefore, the sum of 7 of the interior angles of a regular decagon is 1008°.

Step-by-step explanation:
The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level. In an earlier study, the population proportion was estimated to be 0.19. How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 98% confidence level with an error of at most 0.02
Answer:
A sample of 2084 is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In an earlier study, the population proportion was estimated to be 0.19.
This means that [tex]\pi = 0.19[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 98% confidence level with an error of at most 0.02?
This is n for which M = 0.02. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.02 = 2.327\sqrt{\frac{0.19*0.81}{n}}[/tex]
[tex]0.02\sqrt{n} = 2.327\sqrt{0.19*0.81}[/tex]
[tex]\sqrt{n} = \frac{2.327\sqrt{0.19*0.81}}{0.02}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.327\sqrt{0.19*0.81}}{0.02})^2[/tex]
[tex]n = 2083.4[/tex]
Rounding up:
A sample of 2084 is needed.

Answer:
[tex]Fraction = \frac{3}{5}[/tex]
Step-by-step explanation:
Given
[tex]Fraction = \frac{12}{20}[/tex]
Required
Rename using division
This simply means that we reduce the fraction
So, we have:
[tex]Fraction = \frac{12}{20}[/tex]
Divide by 4/4
[tex]Fraction = \frac{12/4}{20/4}[/tex]
[tex]Fraction = \frac{3}{5}[/tex]

(b)
Find the sale price. (Round your answer to the nearest cent)
Answer:
317.21 (sales price)

Step-by-step explanation:
First, we need to divide.
576.75/100=5.7675 (note that I will be rounding at the end)
5.7675 x 55 (100-45) = 317.2125
Rounds to: 317.21
Now, we need to find the discount amount.
