Step-by-step explanation:
24=3n-15 or,25+15=3n or,39=3n or,39/3=n or,n=13 therefore the value of n is 13. I think this answer is helpful for you
Answer: n = 13
Step-by-step explanation:
24=3(n-5) - First distribute the 3 to the n and the 5. Which you would than get 3n and -15
24=3n-15 - Now add the 15 to both sides which would cause it to cancel out on the left side of the equal side.
39=3n - Now divide the 3 from 3n on both sides of the equal side.
n=13 - Once you do that you will get n = 13. That is your answer!

Answer:
[tex] \huge{ \boxed{ \bold{ \tt{x = 30 \degree}}}}[/tex]
♨ Step - by - step explanation
☯ Given angles :
2x° , 90° , x°☯ To find :
Value of x✎ Set up an equation and solve for x :
[tex] \sf{2x \degree \: + 90 \degree \: + \: x \degree = 180 \degree}[/tex]Add the like terms. Remember that Only coefficients of like terms can be added or subtracted.
➺ [tex] \sf{3x \degree + 90 \degree = 180 \degree}[/tex]
Move 90° to right hand side and change it's sign
➺ [tex] \sf{3x \degree = 180 \degree - 90 \degree}[/tex]
Subtract 90° from 180°
➺ [tex] \sf{3x \degree = 90 \degree}[/tex]
Divide both sides by 3
➺ [tex] \sf{ \frac{3x \degree}{3} = \frac{90 \degree }{3} }[/tex]
➺ [tex] \boxed{ \sf{x = 30 \degree}}[/tex]

❑ Rules for solving an equation
If an equation contains fractions , multiply each term by the LCM of denominators.Remove the brackets, if any.Collect the terms with the variable to the left hand side and constant terms to the right side by changing their signs ' + ' into ' - ' and ' - ' into ' + '.Simplify and get the single term on each side.Divide each side by the coefficient of variable and then get the value of variable.Hope I helped!

An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in California. Suppose that the mean income is found to be $22.4 for a random sample of 2128 people. Assume the population standard deviation is known to be $9.3. Construct the 98% confidence interval for the mean per capita income in thousands of dollars. Round your answers to one decimal place.
Answer:
[21.9, 22.9] in thousands of dollars
Step-by-step explanation:
The formula for Confidence Interval
= Mean ± z score × standard deviation/√n
Mean = $22.4
Standard deviation = $9.3
n = 2128
z score of 98% confidence interval = 2.326
Confidence Interval = 22.4 ± 2.326 × 9.3/√2128
= 22.4 ± 0.469
Confidence Interval =
22.4 - 0.469
= 21.931
≈ 21.9 in thousand of dollars
22.4 + 0.469
= 22.869
≈ 22.9 in thousands of dollars
Hence, the 98% confidence interval =
[21.9, 22.9] in thousands of dollars

In October of 2019, Gallup asked a random sample of 1,506 Americans which of two approaches to punishing murder they thought was better, the death penalty or life without possibility of parole. For the first time since Gallup began asking the question in 1985, a majority of Americans now say life imprisonment is a better approach for punishing murder than is the death penalty. According to the 2019 Gallup death-penalty poll, 60% percent of Americans asked to choose whether the death penalty or life without possibility of parole "is the better penalty for murder" chose the life-sentencing option. 36% favored the death penalty.
Required:
a. Find a 95% confidence interval for the proportion adults in the US that now believe life imprisonment is a better approach for punishing murder.
b. Interpret your interval above in the context of this problem.
c. Use your interval to find the margin of error associated with this confidence interval.
d. If we increase the level of confidence to 98%, will the interval be wider or narrower?
Answer:
a
The 95% confidence interval is [tex]0.5753< p <0.62474[/tex]
b
This 95% confidence interval tell us that there 95% confidence that the true proportion of adults in the US that now believe life imprisonment is a better approach for punishing murder lies within the interval
c
The margin of error is [tex]E = 0.02474 [/tex]
d
The confidence interval becomes wider
Step-by-step explanation:
From the question we are told that
The sample size is n = 1506
The sample proportion is [tex]\^ p = 0.60[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]
=> [tex]E = 1.96 * \sqrt{\frac{0.60 (1- 0.60)}{1506} } [/tex]
=> [tex]E = 0.02474 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex]0.60 - 0.02474 < p <0.60 + 0.02474[/tex]
=> [tex]0.5753< p <0.62474[/tex]
This 95% confidence interval tell us that there 95% confidence that the true proportion of adults in the US that now believe life imprisonment is a better approach for punishing murder lies within the interval
Generally the level of confidence varies directly with the critical value of [tex]\frac{\alpha }{2}[/tex] and this in turn varies directly with the margin of error which when sample proportion is constant it determines the width of the confidence interval so when the level of confidence increases the confidence interval becomes wider

In parallelogram WXYZ, what are the coordinates of the point of intersection of WY and ZX?
Point of Intersection = ____ ____
Answer:
Point of intersection of WY and ZX is (3.5, 3.5).
Step-by-step explanation:
Since, diagonals of a parallelogram bisect each other,
Point of intersection of the diagonals will be midpoint of each diagonal.
By this property, midpoint (x, y) of the segment joining W(-2, 6) and Y(9, 1) will be,
[tex]x=\frac{x_1+x_2}{2}[/tex]
x = [tex]\frac{-2+9}{2}[/tex] = 3.5
Similarly, y-coordinate of the midpoint will be,
y = [tex]\frac{y_1+y_2}{2}[/tex]
y = [tex]\frac{6+1}{2}[/tex] = 3.5
Therefore, point of intersection of the diagonals of the given parallelogram will be (3.5, 3.5).

If three servings of ice cream has 24g of fat, how many milligrams of fat does one serving have?
Answer:
600
Step-by-step explanation:
24 by 3 times 100
The number of milligrams of fat that one serving has is 8000 milligrams.
Firstly, it should be noted that
1000mg = 1 gram.
Since three servings of ice cream has 24g of fat, therefore, the fa that will be contained in each will be:
= 24/3
= 8g
Therefore, we'll convert 8 grams to milligrams and this will be:
= 8 × 1000
= 8000 milligrams.
Therefore, a serving has 8000 milligrams.

Answer:
64 is the measure of angle A.
Step-by-step explanation:
===================================================================
The triangle is an isosceles triangle, so when you use the supplementary theorem for angle BCA and 116, you get 64. And since the base pairs are equal, angle A is 64.
===================================================================
Answer:
m∠A = 64°
Step-by-step explanation:
If AB = BC , then ∠CAB ≅ ∠ACB
m∠ACB = 180° - 116° = 64° ⇒ m∠A = 64°

You need to sketch f given the information you have.
f'(x) is approximately a a cubic polynomial which means f will look like a quartic (think W)
f slopes down (negative slope) to x=2 and then slopes down again...this is a horizontal tangent.
f then slopes down to to x=5 where is has a minimum and then slopes up.
