Answer:

A) a series of t-tests may or may not give you the same conclusion

Step-by-step explanation:

F test is a statistical test, used for testing overall significance in a regression model. It denotes, how well - multiple explanatory (or independent) variables in a regression model effect the variation in dependent variable.

Rejecting a f test implies that - the set of multiple explanatory (or independent) variables 'jointly' effect the dependent variable significantly. However the individual independent variables might or might not effect dependent variable (independently) significantly.

So, the individual t tests might or might not give same conclusion.

Answer:

the annual growth rate is 15.47 %

Step-by-step explanation:

Given the data in the question;

Internet users grew from 25.8 million to 70.6 million,

from the year 2009 to the year 2016.

Using geometric mean, Annual growth rate = ?

To determine the average growth rate of a time series using geometric mean, we use the following formula;

[tex]r_{geo[/tex] = [ [tex]([/tex] Xₙ / X₀ [tex])^{\frac{1}{n}[/tex] ] - 1

where Xₙ is the data value of the last year { 70.6 million }

X₀ is the data value for the first year { 25.8 million }

n is the sample size or the time difference, ( 2016 - 2009 = 7 )

so we substitute;

[tex]r_{geo[/tex] =  [ [tex]([/tex] 70.6 / 25.8  [tex])^{\frac{1}{7}[/tex] ] - 1

[tex]r_{geo[/tex] = [ [tex]([/tex] 2.736434  [tex])^{\frac{1}{7}[/tex] ] - 1

[tex]r_{geo[/tex] = [ 1.15466 ] - 1

[tex]r_{geo[/tex] = 0.15466

[tex]r_{geo[/tex] = ( 0.15466 × 100 )%

[tex]r_{geo[/tex] = 15.47 %

Therefore, the annual growth rate is 15.47 %

Step-by-step explanation:

Hello there I hope you are having an great day :) A chocolate milk container in the form of a rectangular prism is 5 cm long, 3 cm wide, and 9 cm high. How many cubic centimetres of chocolate milk can it hold?

V = L x W x H

Volume = length x Width x Height.

V = (5cm) (3cm (9cm)

V = 135cm^3

Therefore, the chocolate milk container can hold 135 cubic centimetres. Hopefully that helps you :)

length of base is2 inches:

Answer:

Solution given:

According to the questionArea of triangle=14 square inches

bh=14

7*b=14

b=14/7

b=2

length of base is2 inches:

if

A=½bh

then

Area of triangle=14 square inches

½bh=14

½*7*b=14

b=14*2/7

b=4 inches

the length of the base of the triangle is 4inches.

The length of the base of the triangle will be;

⇒ b = 2 inches.

Option 3 is true.

What is mean by Triangle?

A triangle is a three sided polygon , which has three vertices and three angles with sum 180 degree.

Given that;

The area of a triangle = 14 square inches

Height of a triangle = 7 inches

Now,

The given formula for a triangle is;

⇒ A = bh

Where, A is the area, b is base and h is the height of the triangle.

Substitute all the values in above equation, we get;

⇒ A = bh

⇒ 14 = b x 7

Divide by 7, we get;

⇒ 14/7 = b

⇒ b = 2 inches.

Therefore,

The length of the base of the triangle will be;

⇒ b = 2 inches.

Option 3 is true.

Answer:

A. Yes, because by 2206, the radioactive element remaining in the area is less than 800 Bqs.

Step-by-step explanation:

Function for the amount of radioactivity:

The function for the amount of radioactivity, in t years after 1996, is given by:

[tex]f(t) = 14252(0.5)^{\frac{t}{32}}[/tex]

Find f(220) to determine the amount of becqurels in 2206.

[tex]f(220) = 14252(0.5)^{\frac{220}{32}} = 121.42[/tex]

121.42 < 600, so the area will be safe, and the correct answer is given by option A.

Answer:

1725.1 feet

Step-by-step explanation:

It is given that there is a right angled triangle having a base of length of 130 feet. The angle between the hypotenuse and the base is given as 85.691 degrees.

Therefore, to find the height, we know :

[tex]$\tan \theta = \frac{\text{height}}{\text{base}}$[/tex]

[tex]$\tan 85.691 = \frac{\text{h}}{\text{130}}$[/tex]

[tex]$13.27 = \frac{\text{h}}{\text{130}}$[/tex]

h = 13.27 x 130

  = 1725.1 feet

Therefore, the height of the Eiffel tower =  1725.1 feet

Answer:

Total apples=10

no.of honeycrisp Apple=2

1). Probability-2/10. =1/5

now total apples left=9

tolyal honey crisp apples left=1

2) probability=1/9

The Probability that Jerome pick a Honeycrisp apple out of his bag is 1/5.

The Probability the Jerome pick to choose another Honeycrisp apple out of his bag is 1/9.

Probability is "possibility that deals with occurrence random events".

According to the question,

Total number of apples = 10 apples

Total number of Honeycrisp apples = 2 apples

Formula for probability = [tex]\frac{Number of favorable events}{Total number of events}[/tex]

Probability that Jerome pick a Honeycrisp apple out of his bag = [tex]\frac{2}{10}[/tex] = [tex]\frac{1}{5}[/tex].

After taking one honey crisp apple remaining one left so subtracting one from total number of apples.

10 - 1 = 9

Probability that Jerome pick to choose another Honeycrisp apple out of his bag = 1/9.

Hence, the Probability that Jerome pick a Honeycrisp apple out of his bag is 1/5.

The Probability the Jerome pick to choose another Honeycrisp apple out of his bag is 1/9.

Using the Empirical Rule, the percentage of students who scored greater than 700 is:

b. 2.5%

It states that, for a normally distributed random variable:

700 is two standard deviations above the mean. 5% of the measures are more than two standard deviations of the mean. Since the normal distribution is symmetric, 2.5% of these measures are below 300 and 2.5% are above 700, hence option B is correct.

Step-by-step explanation:

The concavity of a function is described by its second derivative.

-The expression will not directly tell us whether the function is concave up or concave down and where it changes, though graphing the function may give us some sort of idea.

-The first derivative tells us the critical/important values (where there could be asymptotes), as well as where the function is increasing/decreasing.

-The second derivative tells us again the critical/important values, but also where the function is concave up/down. We find concavity in the same way we find increasing/decreasing using the first derivative.

-The third derivative, at least in my experience, has only been used to find acceleration of a function.

Hope this helps!! :)

The concavity of a function is described by its 2nd derivative

The concavity of a function is dependent on the rate of change of a function's derivative

Assume the derivative of a function is f'(x), so the second derivative would be represented as: f"(x)

When f"(x) > 0, then the function is concave downward.

However, if f"(x) < 0, then the function is concave upward.

Hence, the concavity of a function is described by its 2nd derivative

Answer:

Since his bro ate 1/6litre...

The remaining is simply

5 - 1/6 = 29/6litres

Sum of the interior angles of any triangle equal 180 degrees , Thus :

A + B + C = 180

48 + B + 67 = 180

B + 115 = 180

B = 180 - 115

B = 65 degrees

Answer:

B = 65°

Step-by-step explanation:

Area of triangle,

→ 180° = A + B + C

→ 180° = 48° + B + 67°

→ 180° = 115° + B

→ B = 180° - 115°

→ B = 65°
