what is 3(4m + 2)
A. 12m + 2
B. 12m + 6
C. 18m
D. 14m

Answers

Answer 1

Answer:

B. 12m + 6

Step-by-step explanation:

Just distribute the 3 to both 4m and 2.

Answer 2

Answer:

B. 12m + 6

Step-by-step explanation:

Because there is a three, we must do three times both of the terms:

(3 x 4m) + (3 x 2)

When you do it, we get:

12m + 6

We cannot simplify it any further, so 12m + 6 is out final answer.

if a circle has a circumference of 100 pi units what is its area

Answers

Step-by-step explanation:

We have,

Circumference of a circle is 100 π.

Formula for circumference is :

[tex]C=2\pi r[/tex]

r is radius of circle

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{100\pi }{2\pi}\\\\r=50\ \text{units}[/tex]

Formula for area of circle is :

[tex]A=\pi r^2\\\\A=\pi (50)^2\\A=2500\pi\ \text{units}^2[/tex]

the area of the circle is 2500π square units.

To find the area of a circle when given the circumference, we must first determine the radius of the circle. The formula for the circumference of a circle is C = 2 π r, where C is the circumference and r is the radius. In this case, the circumference is 100 π units.

We can solve for the radius (r) as follows:C = 2 π r100 π = 2 π rr = 100 π / (2 π)r = 50 units
Now, to find the area (A) of the circle, we use the formula A = π r².

Substitute the radius (50 units) into the area formula:

A = π * (50 units)²A = π * 2500 units²A = 2500 π units²
Therefore, the area of the circle is 2500 π square units.

A random sample of 850 births included 434 boys. Use a 0.10 significance level to test the claim that 51.5​% of newborn babies are boys.

Upper H 0​: pequals0.515 Upper H 1​: pless than0.515 Identify the test statistic for this hypothesis test.

Answers

Final answer:

The null hypothesis is that 51.5% of newborn babies are boys, and the alternative hypothesis is that the percentage is different from 51.5%. The test statistic, used to decide whether to reject or fail to reject the null hypothesis, is calculated using the observed percentage of boys and the sample size.

Explanation:

The question is about testing a hypothesis about the proportion of boys born (51.5%). For this, we set our null and alternative hypotheses. The null hypothesis (H0) being tested here is that the true proportion of boys is 51.5% (p = 0.515), while the alternative hypothesis (H1) is that the proportion of boys is not 51.5% (p ≠ 0.515). The correct choice here would be A: Upper H0: p=0.515, Upper H1: p ≠ 0.515.

To calculate the test statistic, we would use the formula [(p' - p) / sqrt[(p(1 - p) / n]], where p' is the observed proportion in our sample (434 boys out of 850 births or 0.51), p is the claimed proportion (0.515), and n is the sample size (850). After calculating this, you would compare it to a critical value associated with the 0.10 significance level to decide whether to reject or fail to reject the null hypothesis.

Without the specific calculations, I can't tell you what your final test statistic will be, but this should guide you in the right direction.

Final answer:

The null and alternative hypotheses are H₀: p = 0.515 and H₁: p ≠ 0.515. The test statistic for this hypothesis test is the z-score.

Explanation:

The null and alternative hypotheses for this test are:

H₀: p = 0.515H₁: p ≠ 0.515

The test statistic for this hypothesis test is the z-score. To calculate the z-score, you can use the formula:
z = (p' - p₀) / sqrt((p₀ * (1 - p₀)) / n)

Substituting the given values:
z = (434/850 - 0.515) / sqrt((0.515 * (1 - 0.515)) / 850)

Calculating the z-score, we can compare it to the critical value(s) from the standard normal distribution to make a conclusion about the null hypothesis.

fair coin is tossed 3 times in a row. What is the probability that heads appears on only the last toss?

Answers

Answer:

1/1

Step-by-step explanation:

SO the chances are 1/1, or 100%. There are 2^3 = 8 possible outcomes after tossing a fair coin fairly 3 times. The 8 possible outcomes are: TTT, HTT, THT, TTH, HHT, HTH, THH, HHH.

Final answer:

The probability of getting heads only on the last toss of three tosses of a fair coin is 0.25 or 25%. This theoretical probability, according to the law of large numbers, tends to become closer to the observed frequency as the number of repetitions increases.

Explanation:

The subject of this question can be classified under Mathematics. It falls under the area of probability, specifically the concept of binomial probability. When a fair coin is tossed, there are two possible outcomes: heads (H) or tails (T). The probability of getting either outcome is 0.5. This is the theoretical probability based on the assumption that the coin is fair and unbiased.

Tossing the coin three times introduces eight possible combinations (HHH, HHT, HTH, HTT, THH, THT, TTH, TTT). Out of these, only two combinations (TTH, THT) yield heads (H) on the last toss alone.

Therefore, the probability of getting heads only on the last toss is the number of successful outcomes divided by the total number of outcomes, i.e., 2 out of 8 or 0.25 (25%). This probability is a theoretical probability that deals with long-term expectation and it tends to become closer to the observed or empirical frequency as the number of repetitions increases (law of large numbers).

In an aquarium, there are 10 large fish and 5 small fish. Half of the large fish are red.

One fish is selected at random. Find the probability that it is a large, red fish.

Write your answer as a fraction in simplest form.

Answers

Answer: I would think 1/3

Step-by-step explanation:

If there are 10 large fish and half are red that would mean there is a 5/10 chance of getting a red fish from the large fish.. because there are 15 fish in total you would do 5/15 because there are 15 and 10 of those fish are large and 5 of the large fish are red. And 5/15 to its simplest form is 1/3! If this is right please give brainlist!

Final answer:

The probability of randomly selecting a large, red fish from an aquarium with 5 red large fish and 10 total large fish is 1/3.

Explanation:

This question falls under the category of probability in mathematics. In the given aquarium, we have 10 large fish, 5 of which are red, and 5 small fish. That makes a total of 15 fish. So, when you randomly select one fish, you have 15 possible outcomes. If you want to select a large, red fish, you have 5 such fish in the aquarium. The probability of an event is calculated by dividing the number of desired outcomes by the total number of outcomes. Therefore, the probability of selecting a large, red fish from the tank is 5/15 which simplifies to 1/3, this is the fraction in simplest form that represents the probability.

For a normal distribution given a standard deviation of 3.8 in a mean of 54 what percent lies above 48
A 0.1690
B 0.0571
C 0.7660
D 0.9429

Answers

Answer:

choice D.) 0.9429

Step-by-step explanation:

Given a Normal data set

mean u = 54

standard deviation s = 3.8

we want P( X > 48)

Standardize this probability so we can use Z-scores.

P( X > 48) = P( (X - u)/s > (48 - 54)/3.8 ) = P(Z >  -1.5789)

so  I look for P ( Z > 1.5789) = 0.0571

so  P(Z > -1.5789) = 1 - P(Z > 1.5789) = 1 - 0.0571 = 0.9429
