. The mutation causes the same amino acid to be repeated multiple times in the protein product, which results in a linear protein structure.
The mutation causes the wrong amino acid to be incorporated into the protein product, which results in improper protein folding.
The mutation causes the protein product to be lengthened due to an increased number of amino acids being incorporated.

If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

Final answer:

Properties of vertical angles and linear pairs allow us to find unknown angles when two lines intersect by employing the facts that vertical angles are equal and linear pairs sum up to 180 degrees.

Explanation:

When two lines intersect, they form two pairs of vertical angles and two pairs of linear pairs. Vertical angles are opposite angles made by intersecting lines and are always equal. So, if one of the vertical angles is known, the opposite angle can be determined because it is congruent. Linear pairs are adjacent angles whose outer arms form a straight line. These linear pairs are supplementary, meaning their sum is 180 degrees. Therefore, if we know one angle of a linear pair, we can find the other by subtracting the known angle from 180 degrees. Understanding these properties allows us to solve for unknown angle measures around the intersection of two lines. For example, if one angle measure in a linear pair is given, we can find the measure of the adjacent angle. Knowing the measure of this adjacent angle, which is also a vertical angle, allows us to determine the measure of the angle vertical to it, as they are equal.

Final answer:

To find the probability of x successes in a binomial distribution, use the binomial probability formula. Substituting the given values into the formula will yield the probability.

Explanation:

To find the probability of x successes in a binomial distribution with n trials and probability of success p, we use the binomial probability formula. The formula is:

P(x) = (nCx) * p^x * (1-p)^(n-x)

Using the given values n = 4, x = 3, and p = ..., we can substitute these values into the formula to calculate the probability.

For example, if p = 0.5, the probability is:

P(3) = (4C3) * 0.5^3 * (1-0.5)^(4-3) = 4 * 0.125 * 0.5 = 0.25

Answer:

d. 73

The car will average 15 miles per gallon at the speed 73 miles per hour

Step-by-step explanation:

Your equation is: y = 43.81 - 0.395x

We need to solve for x if y = 15

So plug 15 into your equation: 15 = 43.81 - 0.395x

Then rearrange your equation to get the variable by itself and change the sign: 0.395x = 43.81 - 15

Subtract 43.81 - 15 = 28.81

0.395x = 28.81

Then divide both sides of the equation by 0.395

0.395x/0.395 = 28.81/0.395

x = 72.9367088608

Then (Round to nearest whole number.)

Giving you your solution of 73

To Conclude:

The car will average 15 miles per gallon at the speed 73 miles per hour

Answer:

P(Even or ODD) ( .Y .)

Step-by-step explanation:

To fit 68% of women, the store owner should stock shoe sizes between 6 and 9.

To determine the range of shoe sizes that the store owner should order in order to fit 68% of women, we can use the 68-95-99.7 rule, which states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean.

In this case, the mean shoe size is 7.5 and the standard deviation is 1.5. So, we can calculate the range by adding and subtracting one standard deviation from the mean:

Lower Bound = Mean - Standard Deviation

Upper Bound = Mean + Standard Deviation

Therefore, the owner should stock shoe sizes between 6 and 9 to fit 68% of women.

To find (f of f)(0), substitute the value of f(0) into the function and evaluate.

To find (f of f)(0), we need to first find f(f(0)). Given that f(x) = 3x - 2, let's substitute f(0) into the function.

Therefore, (f of f)(0) is equal to -8.

Final answer:

The mean of this probability distribution is 2.

Explanation:

To find the mean of the probability distribution, we need to calculate the expected value. In this case, the random variable is selecting a business major as a success. So, the probability of selecting a business major is 10/25, or 0.4. The number of successes (business majors) in the group project can range from 0 to 5. Using the formula for expected value:

E(X) = p1 * x1 + p2 * x2 + ... + pn * xn,

where pi is the probability of xi occurring, we can calculate the mean as:

E(X) = (0.4 * 0) + (0.4 * 1) + (0.4 * 2) + (0.4 * 3) + (0.4 * 4) + (0.4 * 5)

E(X) = 2

Therefore, the mean of this probability distribution is 2.

Answer:

5 - 6i must also be a root of f(x)

Step-by-step explanation:

Complex conjugates states that the two complex numbers are conjugates of each other if they have the same real part and their imaginary parts are negatives of each other i.e, the complex conjugate of a + bi is a - bi where i is  imaginary.

Conjugate root theorem states that if the complex number a + bi is a root of a polynomial P(x) in one variable with real coefficients, then the complex conjugate a-bi is also a root of that polynomial.

Given: if 5+ 6i is a root of the polynomial function f(x).

then,

by the conjugate root theorem;

5 - 6i is also be a root of the polynomial f(x).

Final answer:

To find the number of calories in 5 ounces of beef, divide 220 calories by 4 ounces to find the per ounce calorie count and then multiply by 5. The answer is 275 calories for 5 ounces of beef.

Explanation:

To determine the number of calories in 5 ounces of beef, we will first calculate the calories per ounce. Given that there are 220 calories in 4 ounces of beef, we can divide 220 calories by 4 to find the number of calories in 1 ounce.

220 calories ÷ 4 ounces = 55 calories per ounce.

Now, if one ounce of beef has 55 calories, then 5 ounces of beef would have:

55 calories/ounce × 5 ounces = 275 calories.

Therefore, 5 ounces of beef contains 275 calories.

To solve this problem, set up a system of linear equations based on the total investment and profit conditions given. Solve for the variables representing investment amounts in black and white film and color film. This process demonstrates practical application of algebra in finance.

Let's find how much was invested in black and white film and color film at a film shop with a total inventory of $4000, knowing that the profit on black and white film is 12%, the profit on color film is 21%, and the profit on color film is $150 less than the profit on black and white film.

Let x represent the amount invested in black and white film, and y represent the amount invested in color film. According to the problem, we have two equations:

First, rearrange Equation 2 to isolate y: 0.12x - 150 = 0.21y. Then, convert it to y = (0.12/0.21)x - (150/0.21).

Next, substitute the value of y from Equation 2 into Equation 1: x + ((0.12/0.21)x - (150/0.21)) = 4000. Solve this equation for x to find the amount invested in black and white film, then substitute x back into either equation to find y, the amount invested in color film.

This problem involves forming and solving a system of linear equations based on the given profit percentages and the condition that profit on color film is $150 less than the profit on black and white film, demonstrating application of algebra in financial contexts.

It will take 40.5 minutes for Car 2 to catch up to Car 1 after its 18-minute head start.

To find out how long it will take for Car 2 to catch up to Car 1, we first need to determine the distance Car 1 travels during the 18-minute head start.

Convert 18 minutes to hours.

18 minutes ÷ 60 minutes/hour = 0.3 hours

Calculate the distance Car 1 travels during the 18-minute head start.

Distance = Speed × Time

Distance = 45 mph × 0.3 hours

Distance = 13.5 miles

Now that we know Car 1 has traveled 13.5 miles when Car 2 starts, we need to find out how long it takes for Car 2 to catch up, which is essentially the time needed to cover this distance at the speed difference between the two cars.

Calculate the relative speed of Car 2 compared to Car 1.

Relative Speed = Speed of Car 2 - Speed of Car 1

Relative Speed = 65 mph - 45 mph

Relative Speed = 20 mph

Calculate the time it takes for Car 2 to catch up.

Time = Distance ÷ Relative Speed

Time = 13.5 miles ÷ 20 mph

Time = 0.675 hours

Convert the time from hours to minutes for better understanding.

0.675 hours × 60 minutes/hour = 40.5 minutes

So, it will take 40.5 minutes for Car 2 to catch up to Car 1 after its 18-minute head start.
