Answer: B

Step-by-step explanation:

Process of elimination:

A: 1 or 2 is 2 favorable outcomes

2/6 or 1/3

one third of 300 is 100, not 50

B: 2, 4, and 6 are even numbers (3 favorable outcomes)

3/6 or 1/2

1/2 of 300 is 150

I say the answer is B. Sorry if I’m wrong.

Answer:

Well, this could turn out to be a simple permutation problem: you have ten number choices (0-9) for each digit of a phone number and repetitions are allowed. Technically, there could be as many as \begin{align*}10^{10} = 10,000,000,000\end{align*}, or 10 billion possible phone numbers.

Answer:

Area of Trapezoid = (b1 + b2)h

                                         2

Area = (9 in + 17 in) (3 in = 1/4 ft)

                      2

A = (26 in)(3 in)/2

A = 78 in2/2

A = 39 in2

Perimeter = bi + b2 + 2l

             P = 9in + 17 in + 2(5 in)

             P = 26 in + 10 in

             P = 36 inches

Step-by-step explanation:

One Pythagorean Triple is 3, 4, 5. 32 + 42 = 52

Any multiple of the three numbers is also a Pythagorean Triple:

Answer:

C

Step-by-step explanation:

It is determined that no subscriber had been selected in the sample more than once the sample had to have been selected without replacement.

A sample is a subset of data drawn from a larger population by a researcher using a predetermined selection process. These components are referred to as sample points, sampling units, or observations.

If it is determined that no subscriber had been selected in the sample more than once, this means that each subscriber was only included once in the sample. This can only occur if the sample was selected without replacement, meaning that each subscriber was selected once and only once from the population frame.

Therefore, the correct answer is C. the sample had to have been selected without replacement.

Step-by-step explanation:

Answer:

335 mm²

Step-by-step explanation:

This will be so easy, that you can do it in the future by yourself!

Okay let's start by splitting this figure, the easiest way seems to be by cutting off that little part, you know what just let me show a picture.

Okay you shuold be able to see the picture, so the small square has an area of 20, since 5 times 4 is 20 mm! The larger square has an area of 315!

How did I find this? Take that small 10mm in the side and add it to 5mm, that would be 15. 15 times the bottom the width, it would be 15 * 21. 15 times 21 is equal to 315.

Now, we add both those areas together, to get ourselves a nice little 335 mm²

I hope that helped, have a great day!!

Answer:

Yes,there is a significant association shell weight and the widths of the opercula

Step-by-step explanation:

Using a correlation Coefficient calculator :

Given the data above :

The Coefficient of correlation(r) obtained is :

0.7632

Obtaining the test statistic :

T = r² / √(1 - r²) / (n - 2)

T = 0.7632² / √(1 - 0.7632²) / (10 - 2)

T = 0.58247424 / 0.2284528

Test statistic = 2.550

The Pvalue from r score , N = 10

Pvalue(0.7632, 10) = 0.01022

α = 0.05

If Pvalue < α ; reject H0

Pvalue < α ; We conclude that there is a significant association shell weights and the widths of the opercula

Answer:

4894

Step-by-step explanation:

Answer:

Round up all costs

Least expensive: $6

Most expensive: $13

Half (half of 12 people is 6) ordered $10 calculators so 6x10=$60

Other half

(6+13)/2= $9.5 round up to $10 so 6x10=$60

$60 + 60=$120 best estimate $125

Step-by-step explanation:

The required, best estimate of the amount spent on calculators is $125.  Option A is correct.

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Since half of the twelve people ordered a calculator costing $9.95, there are 6 such people. Let the remaining 6 people have ordered the cheapest calculator, which costs $5.95. Then the total amount spent on calculators is:

6 x $5.95 + 6 x $9.95 = $35.70 + $59.70 = $95.40

However, we also need to take into account the possibility that some people may have ordered more expensive calculators. We know that the most expensive calculator costs $12.95, so let's assume that all 12 people ordered this calculator. Then the total amount spent on calculators would be:

12 x $12.95 = $155.40

Since the actual amount spent is somewhere between $95.40 and $155.40, the best estimate of the amount spent on calculators is around the midpoint of these values:

($95.40 + $155.40) / 2 = $125.40

Therefore, the best estimate of the amount spent on calculators is $125.

Answer: For A = 35/80 or 43.75% C = 22/80 or 27.5 %

Step-by-step explanation:

I’m not sure if this is right but since 35 students choose A that would be the numerator and the denominator is how many people voted and when you add all 4 options you get 80 so it would be 35/80 and same apply to C which would be 22/80

Answer:

  A.  $45

Step-by-step explanation:

12 hours is 5 more than 7 hours.

Hank will be paid 5 × $9 = $45 if he spends 12 hours working outside.

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

Work Shown:

A = P*(1+r/n)^(n*t)

1000 = 500*(1+0.029/4)^(4*t)

1000 = 500*(1.00725)^(4*t)

1000/500 = (1.00725)^(4*t)

2 = (1.00725)^(4*t)

log(2) = log( 1.00725^(4*t) )

log(2) = 4*t*log( 1.00725 )

4*t*log( 1.00725 ) = log(2)

t = log(2)/( 4*log( 1.00725 ) )

t = 23.9881659971072 The value is approximate

t = 24 when rounding to the nearest full year

Step-by-step explanation:

Answer:

Angle M and N is 45 degrees, and the length of NP is approximately 6 cm

Step-by-step explanation:

With angle P being 90 degrees. The angles of M and N, must add up to 90 degrees as well.

 *triangles add up to a total of a 180 degrees, (180 - 90 = 90)

   9 ÷ 2 = 45

   So: ∠M = 45° and ∠N = 45°

To find the length of NP, use the pythagorean theorem.

a² + b² = c²

a = MP = 5

b = NP = x

c = MN = 7.8

(5)² = 25

(7.8)² = 60.48

25 + x² = 60.48

x² = 60.48 - 25

x² = 35.84

x = √35.84

x = 5.986 = 5.99

NP = 5.99 = 6

Answer:

  5.04 seconds

Step-by-step explanation:

Assuming the ball is in the air until f(x) = 0, we want to find x such that ...

  0 = -5x² +25x +1

  0 = x² -5x -1/5 . . . . . divide by -5

  1/5 = x² -5x . . . . . . . add 1/5

  1/5 +25/4 = (x² -5x +25/4) . . . . complete the square

  129/20 = (x -5/2)² . . . . . . . . . . write as a square

  x = 5/2 +√(129/20) ≈ 5.039685 . . . . square root, add 5/2

The ball stays in the air about 5.04 seconds.
