74. At the gym suppose that 10% of adults belong to health clubs, and 40% of these health club members go to the club at least twice a week. What percent of all adults go to a health club at least twice a week?
Write the information given in terms of probabilities,
and use the general multiplication rule.
The proportion of all adults go to a health club at least twice a week is 4%.
What is percent?
A percentage is a number or ratio expressed as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent sign, "%," is frequently used to indicate it. A percentage is a number without dimensions and without a standard measurement.
Given:
At the gym suppose that 10% of adults belong to health clubs, and 40% of these health club members go to the club at least twice a week.
The proportion of adults who belong to health clubs is 10% that is 0.10.
The proportion of these adults (health club members) go to the club at least twice a week is 40%, that is 0.40.
Hence, the proportion of all adults go to a health club at least twice a week is
0.10 × 0.40 = 0.04, that is 4%

Meteorologists in Texas want to increase the amount of rain delivered by thunderheads by seeding the clouds. Without seeding, thunderheads produce, on average, 300 acrefeet. The meteorologists randomly selected 29 clouds which they seeded with silver iodide to test their theory that average acrefeet is more.What conclusion can they reach based on the above output when they set the significance level to be 0.10?a.The data does not provided statistical evidence that the average acrefeet from seeded clouds is more than 300.b.The data does provide statistical evidence that the average acrefeet from seeded clouds is more than 300.c.The data does not provided statistical evidence that the sample average acrefeet from seeded clouds is more than 300.d.Two of the above are correct.e.We can not draw conclusions based on the above statistical output because the conditions are not met due to the extreme outliers.
The conditions are not met by the extreme outliers, hence we are unable to draw inferences based on the statistical output presented above.
So, option e is correct.
What is meant by null hypothesis?The null hypothesis, often known as H₀, is the assertion that there is no difference between two sets of data or variables under analysis, or that there is no relationship between them. Because there is no underlying causative relationship, the null hypothesis holds that any experimentally detected difference is merely the result of chance; therefore, the name "null."
We can create a z-test hypothesis by assuming that the amount of rain produced by thunderheads follows a distribution that is nearly normal:
300 acre feet is the null hypothesis for the average quantity of rain that thunderheads produce on their own without fertilizing the clouds.
Alternative Hypothesis: The amount of rain that thunderheads often produce by seeding the clouds is greater than 300 acre feet.
This test has a right tail.
So, The conditions are not met by the extreme outliers, hence we are unable to draw inferences based on the statistical output presented above.

By using the fact that all the triangles are equilateral, we will see that AB = 32 units.
What is the length of AB?Here we have a figure made of equilateral triangles. Remember that all the sides of an equilateral triangle have the same measure.
Now we can see that FE = 16, then with that we can conclude that each segment of two consecutive vertices also measures 16 unints.
Now, we can write AB as:
AB = AD + DB
And we know that:
AD = 16 units
DB = 16 units.

mary is going to rent a truck for one day. there are two companies she can choose from, and they have the following prices. company a charges an initial fee of and an additional cents for every mile driven. company b charges an initial fee of and an additional cents for every mile driven. for what mileages will company a charge less than company b? write your answer as an inequality, using for the number of miles driven.
Company A costs less for mileage than Company B, which can be represented by the inequality 0 ≤ m < 85 .
The parameters for the two companies are as follows:
For Company A, the initial cost is $55.
For Company B, the initial cost is $97.50.
The extra cost per mile is 20 cents.
Let us depict the overall fee for company A by C₁ and the total charge for company B by C₂, and we will obtain;
C₁ = 55 + 0.70 × m
C₂ = 97.50 + 0.20 × m
Where "m" stands for the amount of miles driven.
Therefore, the cost of Company A and Company B are the same or equal when have the following relation;
C₁ = C₂
Now we will solve the equation to find the value of m.
∴ 55 + 0.70 × m = 97.50 + 0.20 × m
0.70 × m - 0.20 × m = 97.50 - 55
0.5 × m = 42.5
m = 85
m = 85 miles is the number of miles driven for which both companies will charge the same amount.
As a result, given that Company A's initial fee is smaller than Company B's initial fee, we have;
As a result, Company A charges less than Company B for 0 miles m 85 miles.
Therefore the inequality to represent is given by: 0 ≤ m < 85

BANKING Vera opened a savings account with $3500 that earns 1.1% simple interest annually. After how many years will the balance of the account be $3827.25? Round to the nearest tenth, if necessary.
Answer: It will take about 8.5 years for the balance of the savings account to reach $3827.25.
Step-by-step explanation:
To find the number of years it will take for the balance of the savings account to reach $3827.25, we can set up the following equation:
$3500 * (1 + 0.011 * t) = 3827.25$
We can then solve for t, the number of years, by dividing both sides of the equation by 3500 and then rearranging the terms to get t by itself:
$t = \frac{3827.25 - 3500}{3500 * 0.011}$
Next, we can plug in the given values and solve for t to find the number of years it will take for the balance of the account to reach $3827.25:
$t = \frac{3827.25 - 3500}{3500 * 0.011} = \frac{327.25}{38.5} = 8.5$
Therefore, it will take about 8.5 years for the balance of the savings account to reach $3827.25.

The standard equation of a hyperbola centered at the origin and a vertical tranaverse axis is y²/64 - x²/81 = 1
What is a hyperbola?A hyperbola is a locus of points in such a way that the distance to each focus is a constant greater than one.
What is the standard equation of a hyperbola centered at the origin and a vertical tranaverse axis ?The standard equation of a hyperbola centered at the origin and a vertical tranaverse axis is given by
y²/a² - x²/b² = 1
Now, for the given hyperbola, we have that
a = 8 and b = 9.So, substituting the values of the variables into the equation, we have that
y²/a² - x²/b² = 1
y²/8² - x²/9² = 1
y²/64 - x²/81 = 1
