Answer 1
Answer: A sugestion: calculate m, c, d from:

3m + 4c + 7d = 5.45;
4m + 2c + 8d = 5.30;
2m + 5c + 6d = 5.15;

Then, calculate 10 - (4m + 2c + 9d);

How do I solve for x and state the restriction if (a-c)/(x-a)=m

Answers

(a-c)/(x-a)=m;\ D:x\neq a\n\nm(x-a)=a-c\n\nmx-ma=a-c\n\nmx=a-c+ma\ \ \ \ /:m\neq0\n\nx=(a-c+ma)/(m)

(a - c)/(x - a) = m

(x - a) (a - c)/(x - a) = m ( x - a)

a - c = mx - am

a - c + am = mx

(a)/(m) - (c)/(m) + (am)/(m) = x

(a - c)/(m) + a = x

Brainly for correct answer!!The diagram shows two parallel lines cut by a transversal. One angle measure is shown.


Find the values of A B C D E F and G

Answers

The measure of the angles are a = 54, b = 54, c = 126, d = 54, e = 126, f = 54, and g = 126 degrees.

What are vertically opposite angles?

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

It is given that:

The diagram shows two parallel lines cut by a transversal.

As we know from the definition of the vertically opposite angles:

b = 54 degrees

a + c = 54 + b  (a = c)

2a = 54x2

a = 54 degrees

Since a and g are opposite interior angles, they are congruent, so you proceed with the process as you did for the first and check to see if the angles are acute or obtuse to ensure that the angle measurements are accurate.

Similarly:

b = 54

c = 126

d = 54

e = 126

f = 54

g = 126

Thus, the measure of the angles are a = 54, b = 54, c = 126, d = 54, e = 126, f = 54, and g = 126 degrees.

Answer:

a= 126

b= 54

c= 126

d= 54

e= 126

f= 54

g= 126

Step-by-step explanation:

To find a you would subtract 54 from 180 which would give you 126

Since a and b are another linear pair they would also add up to 180.

Then you move to c which is a linear pair with 54 so it is 126.

Because a and g are alternate interior angles they are congruent and they you continue with the same process for the first and check by seeing if the angles would be obtuse or acute to see if the angle measures would be correct.

Which function has real zeros at x = −10 and x = −6?A. f(x) = x2 + 16x + 60
B. f(x) = x2 − 16x + 60
C. f(x) = x2 + 4x + 60
D. f(x) = x2 − 4x + 60

Answers

Answer:

Option (a) is correct.

f(x)=x^2+16x+60

Step-by-step explanation:

Given :A function has real zeros at x = −10 and x = −6 .

We have to find the function that has real zeros at x = −10 and x = −6.

Consider real zeros at x = −10 and x = −6.

x = - 10 ⇒ x + 10 = 0

x = - 6 ⇒ x + 6 = 0

Multiply both zeroes, we have,

(x+10)(x+6)

Apply Distributive rule,

(a+b)(c+d)=ac+ad+bc+bd

we have,

(x+10)(x+6)=x^2+10x+6x+60

Simplify, we have,

(x+10)(x+6)=x^2+16x+60

Thus, f(x)=x^2+16x+60

Option (a) is correct.

king of brainly (2020)

An epidemiologist is worried about the prevalence of the flu in East Vancouver and the potential shortage of vaccines for the area. She will need to provide a recommendation for how to allocate the vaccines appropriately across the city. She takes a simple random sample of 334 people living in East Vancouver and finds that 43 have recently had the flu. Suppose that the epidemiologist wants to re-estimate the population proportion and wishes for her 95% confidence interval to have a margin of error no larger than 0.03. How large a sample should she take to achieve this?

Answers

Answer:

The sample should be as large as 480

Step-by-step explanation:

Probability of having a flu, p = 43/334

p = 0.129

Margin Error, E = 0.03

Confidence Interval, CI= 95%

At a CI of 95%, z_(crit) = 1.960

The sample size can be given by the relation:

n = p(1-p)(z/E)^(2)

n = 0.129(1-0.129)(1.960/0.03)^(2) \nn = 479.59\nn = 480

Final answer:

To determine the sample size needed to estimate the population proportion with a desired margin of error, we can use the formula n = (z^2 * p * (1-p)) / (E^2), where n is the required sample size, z is the z-score corresponding to the desired level of confidence, p is the estimated proportion of the population with the characteristic, and E is the desired margin of error. Plugging in the given values, the epidemiologist should take a sample size of approximately 3245 in order to achieve her desired margin of error.

Explanation:

To determine the sample size needed to estimate the population proportion with a desired margin of error, we can use the formula:

n = (z^2 * p * (1-p)) / (E^2)

Where:

  • n is the required sample size
  • z is the z-score corresponding to the desired level of confidence (in this case, 95% confidence)
  • p is the estimated proportion of the population with the characteristic (in this case, the proportion of people with the flu in East Vancouver)
  • E is the desired margin of error (in this case, 0.03)

Plugging in the given values:

n = (z^2 * p * (1-p)) / (E^2) = (1.96^2 * 0.129 * 0.871) / (0.03^2) ≈ 3244.42

So, the epidemiologist should take a sample size of approximately 3245 in order to achieve her desired margin of error.
