Answer: Choice B is correct.

==================================================

Explanation:

We are told that the derivative function f ' (x) is positive for all real numbers x. This means that f(x) is increasing for all real numbers. An increasing function goes uphill as you move from left to right. This rules out choices C and D.

We're also told that the integral of f(t), from t = 4 to t = 7, is equal to 0. Because f(x) is increasing, this must mean that some portion of f(x) is below the x axis and some portion is above the x axis when focused on the interval of [tex]4 \le x \le 7[/tex]. This allows us to rule out choice E since there are no portions that are below the x axis here.

At this point, the answer is between A and B. We can rule out choice A for similar reasoning we did with choice E. This time, there is no portion that is above the x axis. We need a negative area (below the x axis) to counterbalance with a positive area (above the x axis) so that the two areas cancel out and add to 0. That doesn't happen with choice A.

The only thing left is choice B so that must be the answer. We have a portion below the x axis and a portion above it, so it's possible that these two areas cancel out to add to 0. Since we don't know the actual f(x) function, it's impossible to tell whether that happens or not.

Answer:

[tex]P(Foreign\ Language\ n\ Sport) = \frac{7}{25}[/tex]

Step-by-step explanation:

Given

See attachment for Venn diagram

Required

Determine [tex]P(Foreign\ Language\ n\ Sport)[/tex]

First, we calculate the population of the set.

This is calculated as:

[tex]Total = Sport + Foreign\ Language + None + Both[/tex]

This gives

[tex]Total = 23 + 10 + 3+14[/tex]

[tex]Total = 50[/tex]

So, the required probability is:

[tex]P(Foreign\ Language\ n\ Sport) = \frac{n(Foreign\ Language\ n\ Sport)}{Total}[/tex]

[tex]P(Foreign\ Language\ n\ Sport) = \frac{14}{50}[/tex]

14 represents the intersection between Foreign and Sport i.e. n(Foreign n Sport)

So, we have:

[tex]P(Foreign\ Language\ n\ Sport) = \frac{7}{25}[/tex]

Answer:

52.38%

Step-by-step explanation:

P(991<X<997) = normalcdf(991,997,993,4) = 0.5328, therefore, about 52.38% of the bottles have volumes between 991 mL and 997 mL

The required proportion of bottles have volumes between 991 mL and 997 mL is 53.28%

Given that,

A bottler of drinking water fills plastic bottles with a mean volume of 993 milliliters (mL),

And standard deviation of 4 ml. The fill volumes are normally distributed.

We have to determine,

What proportion of bottles have volumes between 991 mL and 997 mL.

According to the question,

Mean of the drinking bottle = 993ml

[tex]\mu = 993[/tex]

And standard deviation of = 4 mL

[tex]\sigma = 4[/tex]

The proportion of bottles have volumes between 991 mL and 997 mL is,

[tex]= P (991<X<997) \\\\= P ( \dfrac{991-993}{4} <X < \dfrac{997-993}{4}) \\\\P( -0.5 < X < 1) = 0.5328 = 53.28\ percent[/tex]

Hence, The required proportion of bottles have volumes between 991 mL and 997 mL is 53.28%.

Answer:

0.1248 = 12.48% probability of getting 3 blues.

Step-by-step explanation:

The M&Ms are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

7 + 4 + 4 + 2 + 3 + 3 = 23 total M&Ms, which means that [tex]N = 23[/tex]

Sample of 5 means that [tex]n = 5[/tex]

7 blue means that [tex]k = 7[/tex]

What is the probability of getting 3 blues?

This is P(X = 3).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 3) = h(3,23,5,7) = \frac{C_{7,3}*C_{16,2}}{C_{23,5}} = 0.1248[/tex]

0.1248 = 12.48% probability of getting 3 blues.

Answer:

Step-by-step explanation:

The total cost for the laptop for 3 years is $1174.20.

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

Given that,

Cost of the laptop when purchased = $780

Daily cost = $0.36

Number of days in 3 years = 3 × 365 = 1095 days

Cost for the laptop for 3 years = 1095 × $0.36

                                                   = $394.20

Total 3 year cost = $394.20 + $780

                            = $1174.20

Hence the total cost for the laptop is $1174.20.

Answer:

A. 55°

Step-by-step explanation:

Complementary angles are angles that add up to give us 90°.

Since <A and <B are complementary angles, it implies that:

m<A + m<B = 90°

If m<A = 35°, therefore:

35° + m<B = 90°

Subtract 35° from each side

m<B = 90° - 35°

m<B = 55°
