Answer: 75%
Step-by-step explanation:
First: work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Then: divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
Decrease =240- 60
Decrease = 180
180 /240=0.75 * 100 = 75%
The percent of decrease = 75%
2. P337. 23. A large box contains 10,000 ball bearings. A random sample of 120 is chosen. The sample mean diameter is 10 mm, and the standard deviation is 0.24 mm. True or false: (a) A 95% con dence interval for the mean diameter of the 120 bearings in the sample is 1 ???? (1:96)(0:24)= p 120. (b) A 95% con dence interval for the mean diameter of the 10,000 bearings in the sample is 1 ???? (1:96)(0:24)= p 120. (c) A 95% con dence interval for the mean diameter of the 10,000 bearings in the sample is 1 ???? (1:96)(0:24)= p 10; 000.
Answer:
B is True
A, C. D are false
Step-by-step explanation:
Given :
Sample size, n = 120
Mean diameter, m = 10
Standard deviation, s = 0.24
Confidence level, Zcritical ; Z0.05/2 = Z0.025 = 1.96
The confidence interval represents how the true mean value compares to a set of values around the mean computed from a set of sample drawn from the population.
The population here is N = 10000
To obtain
Confidence interval (C. I) :
Mean ± margin of error
Margin of Error = Zcritical * s/sqrt(n)
Margin of Error = 1.96 * 0.24/sqrt(120)
Confidence interval for the 10,000 ball bearing :
10 ± 1.96 * (0.24) / sqrt(120)
Hence. The confidence interval defined as :
10 ± 1.96 * (0.24) / sqrt(120) is the 95% confidence interval for the mean diameter of the 10,000 bearings in the box.
A bridge connecting two cities separated by a lake has a length of 5927.261 yd. use the table of facts to find the length of the bridge in miles. Round your answer to the nearest tenth.
Answer:
the length of the bridge in miles is 3.37 miles
Step-by-step explanation:
The computation of the length of the bridge in miles is shown below:
Given that
The length is 5927.261 yard
As we know that
1760 yard = 1 mile
So 1 yard = 1 ÷ 1760 mile
For 5927.261 yard, the miles would be
= 5927.261 ÷ 1760
= 3.37 miles
Hence, the length of the bridge in miles is 3.37 miles

∠3 and ∠6 are alternate interior angles. If m∠3 = 75, what is the measure of ∠6
a. 15°
b. 75°
c. 105°
d. 180°
Answer:
B. m<3 = m<6 = 75degreesStep-by-step explanation:
First you must understand that in geometry, the alternate interior angles are equal
Hence if ∠3 and ∠6 are alternate interior angles, then <3 = <6
Given that m<3 = 75 degrees
m<6 will also be 75 degrees since both angles are equal

Stacy opens an account with a deposit of $100. She deposits an additional $25 every week after opening the account. Determine how much money will be in her account after 15 weeks.
Answer:
$450
Explanation:
after 15 weeks, stacy would have deposited a total of $25 × (15 - 1) = $350. (remember to subtract 1 from the 15 weeks since she did not deposit $25 during the week she opened the account, but only after that.)
now, we need to add this to the original deposit: $100 + $350 = $450.
therefore, after 15 weeks, there would be $450 in her account.

∫(cos3x+3sinx)dx integration
Answer:
[tex] I = \dfrac{1}{3}sin(3x) - 3cos(x) + C[/tex]
Step-by-step explanation:
We need to integrate the given expression. Let I be the answer .
[tex]\implies\displaystyle I = \int (cos(3x) + 3sin(x) )dx \\\\\implies\displaystyle I = \int cos(3x) + \int sin(x)\ dx [/tex]
Let u = 3x , then du = 3dx . Henceforth 1/3 du = dx .Rewrite using du and u .[tex]\implies\displaystyle I = \int cos\ u \dfrac{1}{3}du + \int 3sin \ x \ dx \\\\\implies\displaystyle I = \int \dfrac{cos\ u}{3} du + \int 3sin\ x \ dx \\\\\implies\displaystyle I = \dfrac{1}{3}\int \dfrac{cos(u)}{3} + \int 3sin(x) dx \\\\\implies\displaystyle I = \dfrac{1}{3} sin(u) + C +\int 3sin(x) dx \\\\\implies\displaystyle I = \dfrac{1}{3}sin(u) + C + 3\int sin(x) \ dx \\\\\implies\displaystyle I = \dfrac{1}{3}sin(u) + C + 3(-cos(x)+C) \\\\\implies \boxed{\boxed{\displaystyle I = \dfrac{1}{3}sin(3x) - 3cos(x) + C }}[/tex]

Write an equation for the function graphed above.
Answer:
I think that the equation would be = |X - 2|
Step-by-step explanation:
Hope it was helpful :)
The equation for the function graphed above is [tex]g(x) = |x-2| + 1[/tex].
The expression of [tex]g(x)[/tex] is the consequence of translating both horizontally and vertically regarding [tex]f(x)[/tex], which it can be defined by following expression:
[tex]g(x) = f(x - h) + k[/tex] (1)
[tex]f(x)[/tex] - Original function.[tex]g(x)[/tex] - Resulting function.[tex](h,k)[/tex] - Coordinates of the "center" of the resulting function.
If we know that [tex](h,k) = (2, 1)[/tex] and [tex]f(x) = |x|[/tex], then the resulting function is:
[tex]g(x) = |x-2| + 1[/tex]
The equation for the function graphed above is [tex]g(x) = |x-2| + 1[/tex].

Three sixth-grade classes raised $25.50, $49.75,
and $37.25 for their classroom libraries. They agreed to
share the money raised equally. What is each class’s equal share?
Answer:
$37.50
Step-by-step explanation:
They are asking you to find the average and to do that you have to add all the numbers together in a given set then divide that total by the amount of numbers in that set to get your average.
Answer:
The answer is, 37.50
Step-by-step explanation:
Definition of spread out and share:In statistics, spread refers to a data set's variability, or how the data is spread out and differs from the mean.
The range, quartiles, deciles, and percentiles; the five-number summary; standard deviation, and variance are all examples of spread measures.
According, to the question:
Adding the all the value, 25.50, 49.75,and 37.25
= 25.50+49.75+37.25
= 112.5
To get your average, divide the sum by the number of numbers in the set.
= 112.5/3
= 37.50
The equal share of the class is 37.50.
