Answer:

The probability is 0.508 = 50.8%.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Normally distributed with a mean weight of 0.8544 g and a standard deviation of 0.0525 g.

This means that [tex]\mu = 0.8544, \sigma = 0.0525[/tex]

If 1 candy is randomly​ selected, find the probability that it weighs more than 0.8535 g.

This is 1 subtracted by the pvalue of Z when X = 0.8535. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0.8535 - 0.8544}{0.0525}[/tex]

[tex]Z = -0.02[/tex]

[tex]Z = -0.02[/tex] has a pvalue of 0.492

1 - 0.492 = 0.508

The probability is 0.508 = 50.8%.

Answer:

  (b) ΔPQR ~ Δ STR, PR = 16, SR = 12

Step-by-step explanation:

The similar triangles are ...

  ΔPQR ~ ΔSTR . . . . by AA similarity: S ≅ P; ∠SRT ≅ ∠PRQ

Corresponding sides are proportional, so we have ...

  PR/PQ = SR/ST

  (x +1)/8 = (x -3)/6

  3(x +1) = 4(x -3) . . . . . . multiply by 24

  3x +3 = 4x -12 . . . . . . . eliminate parentheses

  15 = x . . . . . . . . . . . . . . add 12-3x

Then the side lengths are ...

  PR = x+1 = 15 +1 = 16

  SR = x -3 = 15 -3 = 12

The similarity statement and side lengths match the 2nd choice.

Answer:

the problem is asking you to divide (16-2) by (7-5)

14 / 2

The answer is 7

Step-by-step explanation:

The expression for the calculation of the quotient of 16 minus 2 and 7 minus 5 is (16-2)/(7-5) and the solution of this equation is 7.

Quotient is the resultant number which is obtained by dividing a number with another. Let a number is divided by number b. Then the quotient of these two number will be,

[tex]q=\dfrac{a}{b}[/tex]

Here, (a, b) are the real numbers.

The expression for the calculation of the quotient of 16 minus 2 and 7 minus 5 has to be written.

Let n, is the required expression. Thus,

[tex]n=\dfrac{16-2}{7-5}[/tex]

Solve it further,

[tex]n=\dfrac{14}{2}\\n=7[/tex]

Thus, the expression for the calculation of the quotient of 16 minus 2 and 7 minus 5 is (16-2)/(7-5) and the solution of this equation is 7.

Answer:  10 feet

Step-by-step explanation:

Answer:

By the time she achieves her 26 mile goal Andrea will have run 176 miles.

Step-by-step explanation:

Since Andrea runs 4 miles every day, but she wants to increase her distance in order to run a 26 mile marathon and she decides to add 2 miles each day to her distance until she achieves her goal, to determine, if she starts with 6 miles today, how many miles will she have run in total, by the time she achieves her 26 mile goal the following calculation should be performed:

6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26 = X

14 + 22 + 30 + 38 + 46 + 26 = X

36 + 68 + 72 = X

36 + 140 = X

176 = X

So, by the time she achieves her 26 mile goal Andrea will have run 176 miles.

Answer:

y = 3/4x + 6

Step-by-step explanation:

(-4,3) and (-8,0)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(0 - 3) / (-8 - (-4))

Simplify the parentheses.

= (0 - 3) / (-8 + 4)

= (-3) / (-4)

Simplify the fraction.

= -3/-4

= 3/4

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = 3/4x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-8, 0). Plug in the x and y values into the x and y of the standard equation.

0 = 3/4(-8) + b

To find b, multiply the slope and the input of x(#)

0 = -6 + b

Now, add 6 to both sides to isolate b.

6 = b

Plug this into your standard equation.

y = 3/4x + 6

This is your equation.

Check this by plugging in the other point you have not checked yet (-4, 3).

y = 3/4x + 6

3 = 3/4(-4) + 6

3 = -3 + 6

3 = 3

Your equation is correct.

Answer:

5.5×5.5=30.5

we rounded 30.25 in nearest tenth it becomes 30

Answer:

C.] 5.5

Step-by-step explanation:

It is mentioned that the number was multiplied by the number itself.

Let's take 'x' as the number. It was multiplied by itself and the product is 30. So the equation will be:

x × x = 30

[tex]x^{2}[/tex] = 30

x = [tex]\sqrt{30}[/tex]

x = 5.47 = 5.5 (to the nearest tenth)

Answer:

B

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals. For example. if the slope of a line is 2, the slope of a line perpendicular to it would be [tex]-\frac{1}{2}[/tex]. If the slope of a line [tex]-\frac{1}{3}[/tex], the slope of a line perpendicular to it would be 3.

Negative reciprocals always have a product of -1, since the numerators cancel out and one of the values is negative.

= Area of square with side 40 ft + Area of semicircle with radius (40/2) i.e. 20 ft

[tex] = {(40)}^{2} + \frac{1}{2} \times 3.14 \times {(20)}^{2} \\ \\ = 1600 + \frac{1}{2} \times 3.14 \times 400 \\ \\ = 1600 + 3.14 \times 200 \\ \\ = 1600 + 628 \\ \\ = 2228 \: {ft}^{2} [/tex]

8 × 9 = 72

33 + 72 = 105

The answer is 105

31 - 20 = 11

11 × 3 = 33

The answer is 33

102 - 6 = 8 - 5

102 - 6 = 96

96 = 8 - 5

8 - 5 = 3

96 = 3

93 = 3 is false so therefor, this equation has no solution.

4th Equation:

102 = 12 + 4 × 7 - 2

4 × 7 = 28

102 = 12 + 28 - 2

12 + 28 = 40

102 = 40 - 2

40 - 2 = 38

102 = 38

102 = 38 is false so, it means that this equation has no solution.
