Total n( S) = 750

The probability of having high cholesterol level

                           P( E) = [tex]\frac{n(E)}{n(S)} = \frac{372}{750} = 0.496[/tex]

Answer:

A.

Step-by-step explanation:

The expression (1/4) * d + 7 really just means "one-fourth times d, plus 7"

Option A says the same expression, as we know that the product means multiplication, and that we add 7 at the end. For this reason, it is the correct response.

Answer & Step-by-step explanation:

For this problem, all we have to do is multiply the two expressions.

f(x) = 3x + 1

g(x) = x² - 6

Now, let's set up our equation for multiplication.

(f * g)(x) = (3x + 1)(x² - 6)

(f * g)(x) = 3x³ - 18x + x² - 6

(f * g)(x) = 3x³ + x² - 18x - 6

So, (f * g)(x) is 3x^3 + x^2 - 18x - 6

the correct Answer is

3x^3+x^2-18x-6

Answer:

(b + 3)(4b + 5)

Step-by-step explanation:

Given

4b² + 17b + 15

Consider the factors of the product of the b² term and the constant term which sum to give the coefficient of the b- term.

product = 4 × 15 = 60 and sum = 17

The factors are 12 and 5

Use these factors to split the b- term

4b² + 12b + 5b + 15 ( factor the first/second and third/fourth terms )

= 4b(b + 3) + 5(b + 3) ← factor out (b + 3) from each term

= (b + 3)(4b + 5) ← in factored form

Answer:

18

Step-by-step explanation:

Let's call the first number n. The next four numbers will be n + 3, n + 6, n + 9 and n + 12. Then, we have

n + n + 3 + n + 6 + n + 9 + n + 12 = 105

5n + 30 = 105

5n = 75

n = 15

The second smallest number is n + 3 which is 15 + 3 = 18.

The denominator is the bottom number in a fraction, while the numerator is the top number.

numerator/denominator

Let's analyze the answer choices.

A. 6 2/3

The bottom number of the fraction is a 3, so this cannot be correct.

B. 16/18

The denominator here is 18, so this choice is also incorrect.

C. 6/7

In this fraction the numerator is a 6, but the denominator is a 7, so this choice is also wrong.

D. 1/6

This choice is the correct answer. The denominator, or bottom number is a 6.

The answer is D. 1/6.

Complete Question:

A population proportion is 0.4. A sample of size 200 will be taken and the sample proportion p will be used to estimate the population proportion. Use z- table Round your answers to four decimal places. Do not round intermediate calculations. a. What is the probability that the sample proportion will be within ±0.03 of the population proportion? b. What is the probability that the sample proportion will be within ±0.08 of the population proportion?

Answer:

A) 0.61351

Step-by-step explanation:

Sample proportion = 0.4

Sample population = 200

A.) proprobaility that sample proportion 'p' is within ±0.03 of population proportion

Statistically:

P(0.4-0.03<p<0.4+0.03)

P[((0.4-0.03)-0.4)/√((0.4)(.6))/200 < z < ((0.4+0.03)-0.4)/√((0.4)(.6))/200

P[-0.03/0.0346410 < z < 0.03/0.0346410

P(−0.866025 < z < 0.866025)

P(z < - 0.8660) - P(z < 0.8660)

0.80675 - 0.19325

= 0.61351

B) proprobaility that sample proportion 'p' is within ±0.08 of population proportion

Statistically:

P(0.4-0.08<p<0.4+0.08)

P[((0.4-0.08)-0.4)/√((0.4)(.6))/200 < z < ((0.4+0.08)-0.4)/√((0.4)(.6))/200

P[-0.08/0.0346410 < z < 0.08/0.0346410

P(−2.3094 < z < 2.3094)

P(z < -2.3094 ) - P(z < 2.3094)

0.98954 - 0.010461

= 0.97908

Step-by-step explanation:

The opposite angles of a parallelogram are equal.

Answer:

Step-by-step explanation:

If triangles MNO and PQR are similar, then the corresponding sides are propotional and the corresponding angles are congruent.

So, we know by gvein that angles O and R are congruent. We only need another angle congruence to use the AA postulate of similarity.

Therefore, the right answer is the second choices, because Angle N must be congruent to Angle Q.

Answer: B: Angle N isn’t congruent to angle Q

Step-by-step explanation: You have to follow the letters MNO and PQR. We know O is congruent to R to get another angle we would use Angle N and Q because of the order since Angle M and angle Q aren’t in the same order and we’re not dealing with sides only Angles.

The westerly and northerly components of the velocity of a flying airplane are 343.5 km/h and 66.7 km/h respectively.

Given in the question,

The airplane is flying at 350km/h in a direction of 349 degrees.

so, the airplane is flying 360-349=11degrees from the east as shown in the image.

The northerly component is 350*sin11degrees and the westerly component is 350*cos11degrees.
