Jerome went apple picking with his family. In his bag he had four Granny Smith
apples, two Honeycrisp apples, three Gala apples, and one Fuji apple. What is
the probability that he will pick a Honeycrisp apple out of his bag, eat it, and
then choose another Honeycrisp apple? Write your answer as a simplified
fraction.
Answers
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.
What is probability?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.

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°

The College Board originally scaled SAT scores so that the scores for each section were approximately normally distributed with a mean of 500 and a standard deviation of 100. Assuming scores follow a bell-shaped distribution, use the empirical rule to find the percentage of students who scored greater than 700.
a. 95%.b. 2.5%.c. 5%.d. 97.5%.
Answers
Using the Empirical Rule, the percentage of students who scored greater than 700 is:
b. 2.5%
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.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.

A right triangle has a a vertical side as the height of the Eiffel Tower, a horizontal side of length 130 feet across the ground, and an unlabeled hypotenuse. The angle formed by the hypotenuse and the horizontal side measures 85.691 degrees. 130 ft The height of the tower is nothing feet.
Answers
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

the concavity of a function is described by its

Answers
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

The number of Internet users in Latin America grew from 25.8 million in 2009 to 70.6 million in 2016. Use the geometric mean to find the annual growth rate. (Round your answer to 2 decimal places.)
Answers
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 %

In April 1986, a flawed reactor design played a part in the Chernobyl nuclear meltdown. Approximately 14252 becqurels (Bas), units of radioactivity, were initially released into the environment. Only areas with less than 800 Bas are considered safe for human habitation. The function f) = 14252(0.5) describes the amount, (), in becqurels, of a radioactive element remaining in the area of years after 1986. Find f(220) to determine the amount of becqurels in 2206. Determine if the area is safe for human habitation in the year 2206.
A. Yes, because by 2206, the radioactive element remaining in the area is less than 800 Bqs.
B. No, because by 2206, the radioactive element remaining in the area is greater than 800 Bqs.
C. Yes, because by 2206, the radioactive element remaining in the area is greater than 800 Bqs.
D. No, because by 2206, the radioactive element remaining in the area is less than 800 Bqs.
Answers
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.

If you reject a joint null hypothesis using the F-test in a multiple hypothesis setting, then: A) a series of t-tests may or may not give you the same conclusion. B) the regression is always significant. C) all of the hypotheses are always simultaneously rejected. D) the F-statistic must be negative. Answer: A
Answers
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.
