Answer:

21

Step-by-step explanation:

Let the three consecutive integers be;

    x , x + 1 and x + 2:

The sum of squares of the two smaller numbers:

  The two smaller numbers are x and x+ 1

Sum of their squares:

           x² + (x+1)²;

        x² + x² + 2x + 1 = 2x² + 2x + 1

It is 45 more than the square of the larger number:

    Larger number = x + 2

        (x+2)² = x² + 4x + 4

 45 more;

        x² + 4x + 4 + 45  = x² + 4x + 49

Both are equal:

 2x² + 2x + 1 =  x² + 4x + 49  

  2x² - x² + 2x - 4x + 1 - 49 = 0

      x² - 2x - 48 = 0

      x² - 6x + 8x - 48 = 0

      x(x - 6) + 8(x - 6) = 0

      (x + 8)(x-6) = 0

      x + 8 = 0 or x - 6 = 0

      x  = -8 or x = 6

We choose x = 6 because it makes the solution true as a positive integer

  Sum of the three numbers:

     x + x + 1 + x + 2 = 6 + 6 + 1 + 6 + 2 = 21

The statement (D) The results of all previous events do not affect the probability of future events best describes independent events option (D) is correct.

An independent event is one that is unaffected by other events. The occurrence of one event has no bearing on the other.

We have a statement:

Which best describes independent events?

As we know from the definition of independent events, the events that is unaffected by other events.

Also, the probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Thus, the statement (D) The results of all previous events do not affect the probability of future events best describes independent events option (D) is correct.

287-54=233

here is the correct answer

There are 4 quarters in the box of coins.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

A box of coins contains nickels, dimes and quarters.

The value of the coins is $4.00.

And, There were 3 times as many nickels, half as many dimes, and 6 more quarters, the value of the coins would be $5.50.

Now,

Let number of nickels in a box = n

Number of dimes = d

Number of quarters = q

Here, The value of the coins is $4.00.

Hence, We get;

⇒ 5n + 10d + 25q = 400 cents   .... (i)

And, There were 3 times as many nickels, half as many dimes, and 6 more quarters, the value of the coins would be $5.50.

Hence, we get;

⇒ 3(5n) + 5d + 25(q+6) = 550 cents

⇒ 15n + 5d + 25q + 150 = 500

⇒ 15n + 5d + 25q = 350   .. (ii)

After solving equation (i) and (ii), we get;

Number of nickels in a box = n = 12

Number of dimes = d = 24

Number of quarters = q = 4

Answer:

1. the perimeter of the first question is 22.5

2. true

5. 16.25

these are the only ones i remember how to do!

sorry :(

Hopefully someone fills in the rest of the answers!!!

Answer:

Question 1:

8/12 = 4/6 = 3/x

0.6 = 0.6 = 3/x

It is a similar triangle, therefore 3/x = 0.6

x = 5 because 3/5 = 0.6

Question 2

You did that correct :)

Question 3:

"Check all that apply"

B

D

Question 4

You got question 4 wrong since similar triangles have similar ratio.

8/10 = 8/10 = 10/14

0.8 = 0.8 = 0.7

Correct answer for question 4 is B("No they are not similar because the ratios are not equal")

Question 5

The Quadrilaterals are similar. Therefore:

22.4/14 = 12.8/8 = 12/7.5 = 26/x

1.6 = 1.6 = 1.6 = 26/x

Meaning 26/x = 1.6

x = 16.25

Because 26/16.25 = 1.6

Answer:

2/5

Step-by-step explanation:

first select the line that is positive which is the purple one

slope = change in y / change in x

two clear points are (0,2) and (5,4)

so you do y2-y1 / x2-x1

=(4-2)/(5-0)

=2/5

so the slope is 2/5

Answer:

Parker the dog is 76.2 centimeters long.

Step-by-step explanation:

Parker the dog is 2 feet 6 inches long. There are 2.54 centimeters in 1 inch. How many centimeters is Parker the dog?​ 2 feet = 12 inches. 2(12) + 6 = 30

30(2.54) = 76.2.

Please let me know if you have anymore questions.

Good Luck! :)

1 foot = 12 inches

1 inch = 2.54 centimeters

1 foot = 30.48 centimeters

2 x 30.48 =  60.96

6 x 2.54 = 15.24

60.96+15.24=76.20

Parker the Dog is 76.20 centimeters tall.

Answer:

The formula you'll need is:

Years = ln (total / principal) / rate

ln means natural log

Years = ln (2,000 / 1,000) / .045

Years = ln (2) / .045

Years = 0.69314718056 / .045

Years = 15.4033

Answer:

The minimum sample size required is 1068.

Step-by-step explanation:

The complete question is:

A researcher wishes to​ estimate, with 95​%  confidence, the population proportion of adults who eat fast food four to six times per week. Her estimate must be accurate within 3​%  of the population proportion.

​No preliminary estimate is available. Find the minimum sample size needed.

Solution:

The (1 - α)% confidence interval for the population proportion is:

[tex]CI=\hat p\pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

The margin of error for this interval is:

[tex]MOE= z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

The information provided is:

[tex]MOE=0.03\\\text{Confidence level}=95\%[/tex]

Assume that the sample proportion is 50%.

The critical value of z is, 1.96.

Compute the minimum sample size required as follows:

[tex]MOE= z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

      [tex]n=[\frac{z_{\alpha/2}\cdot \sqrt{\hat p(1-\hat p)}}{MOE}]^{2}[/tex]

         [tex]=[\frac{1.96\times\sqrt{0.50(1-0.50)}}{0.03}]^{2}\\\\=1067.1111\\\\\approx 1068[/tex]

Thus, the minimum sample size required is 1068.

Answer:

  range: 5 ≤ f(x) ≤ 205

Step-by-step explanation:

You can put the extreme values of x in this linear function to see its range:

  f(0) = 4·0 +5 = 5

  f(50) = 4·50 +5 = 205

The range is 5 ≤ f(x) ≤ 205.

Answer:

False

Answer:

  10, 12, 14   and maybe {8, 10, 12} and {12, 14, 16}, depending on the meaning of the question

Step-by-step explanation:

If x is the middle one, then their sum is 3x. You want ...

  15 < 3x/2 < 21 . . . . assuming "between 15 and 21" does not include 15 or 21

  30 < 3x < 42

  10 < x < 14

The only even integer in that range is 12, so the three integers are ...

  10, 12, 14 . . . . . half their sum is 18

__

We have used <, rather than ≤ in the above solution. This assumes that "between" does not include the values at the end of the range. If those values are included, then two additional solutions are possible: {8, 10, 12} and {12, 14, 16}. For the first set, the half-sum is 15; for the second set, the half-sum is 21.

Answer:

X = 6

Step-by-step explanation:

150 - 3x = 120 + 2x

150 = 120 + 5x

30 = 5x

6 = x

x = 6

The solution to the equation is x = 6.

To solve this equation 150 - x - 2x = 120 +2x , we need to isolate the variable x.

To simplify the equation ;

Distribute the negative sign to the terms inside the parentheses:

150 - x - 2x = 120 + 2x

150 - 3x = 120 + 2x

Combine like terms on both sides of the equation:

-3x - 2x = 120 - 150

-5x = -30

Divide both sides of the equation by -5 to solve for x:

-5x / -5 = -30 / -5

x = 6

Therefore, the solution to the equation is x = 6.

Answer:

30

Step-by-step explanation:

59 divided by 1/2 or 2 is 29.5 which round up to 30

The round-off to the number 59 is 59.5 to the nearest half.

When a number is rounded off, it is approximated to a specific level of precision or place value. You may simplify or make a number easier to work with while still retaining a fair degree of precision by rounding it off.

To round a number to the nearest half, find the nearest half-number (0.5, 1.0, 1.5, etc.). The decimal place immediately to the right of the half is taken into account since we are trying to get the closest half in this situation.

The digit after the decimal point in the number 59 is 9. We round up since 9 is larger than 5, not 5. Consequently, the outcome is 59.5 after rounding 59 to the closest half.
