Answer:

C, 0.30

Step-by-step explanation:

First, simplify.

[tex]\frac{15}{50}[/tex] = [tex]\frac{3}{10}[/tex]

Next, divide

3 ÷ 10 = 0.30 or 0.3

To Find:

We know that:

Where,

Finding the probability that a car arriving at this intersection will not fully stop:

⟶ P(E) = 15/50

Multiply by 2 with both numerator and denominator.

⟶ P(E) = (15 × 2)/(50 × 2)

⟶ P(E) = 30/100

⟶ P(E) = 0.30

Hence,

Step-by-step explanation:

15 : 45

Divide both sides by 15

1 : 3

20 : 60

Divide both sides by 20

1 : 3

25 : 75

Divide both sides by 25

1 : 3

When you deposit cash at a bank or credit union, you typically need to use a deposit slip. That's simply a slip of paper that tells the teller where to put the money. Write your name and account number on the deposit slip (deposit slips are usually available at the lobby or drive-throug).

Answer:

8,333 total population

Step-by-step explanation:

Question can be restated as "5000 is 60% of what number?"

5000 = .6x

x = 5000/0.6

x = 8,333.33

Answer:

Option D. 37¼ ft

Step-by-step explanation:

The perimeter of the figure above can be obtained by adding all the lengths of each sides together. This can be obtained as follow:

The lengths of each sides are given below:

Top = 6¼ ft

Left = 9⅛ ft

Bottom = 9½ ft

Right = 7¾ ft

Top horizontal = 9½ – 6¼

= 19/2 – 25/4

= 13/4 ft

Top height = 9⅛ – 7¾

= 73/8 – 31/4

= 11/8 ft

Perimeter = 6¼ + 9⅛ + 9½ + 7¾ + 13/4 + 11/8

= 25/4 + 73/8 + 19/2 + 31/4 + 13/4 + 11/8

= 149/4

= 37¼ ft

Thus, the perimeter of figure is 37¼ ft

Answer:

Ecological study

Step-by-step explanation:

When the basis for the conclusion of a study is done an a group or population level rather than on a person, single or individual basis, then we refer to this as an ecological study. In the scenario described above, relationship between ozone in Pennsylvania and the number of asthma cases was generalized and presented on the mean or average level rather than being compared in terms of individual figure. Hence, research studies of this type or nature are classed as ecological study.

Answer:

Step-by-step explanation:

Answer:

144 seconds

Step-by-step explanation:

divide 90 by 15 to get 6

if you are jumping in sets of 15, that means you need to jump 6 sets to get to a total of 90 jumps total. if every set of 15 jumps takes 24 seconds that means that 6 sets will take 144 seconds. 6 x 24 = 144

Answer:

M

Step-by-step explanation:

Answer:

I believe your answer is 92.

Step-by-step explanation: Usually, a picture frame is in the shape of a square or rectangle. So to find area you use length times width, correct? Since the opposite side of each side on a rectangle or square is the same value, then that means your answer is probably double that of the area. Giving you 92 :) I hope this helped a bit!

I calculated logically

Answer:

a. The sample of 500 is too small to permit drawing conclusions about elementary students in general.

C. Even though students who did well in school watched less television, this doesn't necessarily mean that watching television hurts school performance.

Step-by-step explanation:

To make inferences about a general population from sample data, we must ensure that the data is considerably large enough and randomized, this is in other to ensure that the sample is representative of the population. Hence, Making conclusion about a very large population such as here, where we want to correlate performance and playing time, a very large sample which should be atleast 10% of the population should be employed. Hence, a sample of 500 ; for making Decison about general elementary students which should run into millions require more samples.

Also Recall that, correlation does not imply causation, The fact that there is a perceives relationship between grade or performance and time spent watching TV does not necessarily mean that poor grade was caused by long duration of hours spent watching television. Other, factors such as, level of intelligence, variation of teachers competence and so on may also be causal factors.

Answer:

x = - 2, x = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Given

(2x + 4)(3x - 2) = 0

Equate each factor to zero and solve for x

2x + 4 = 0 ( subtract 4 from both sides )

2x = - 4 ( divide both sides by 2 )

x = - 2 ← lesser x

3x - 2 = 0 ( add 2 to both sides )

3x = 2 ( divide both sides by 3 )

x = [tex]\frac{2}{3}[/tex] ← greater x

Answer:

Option D.

Step-by-step explanation:

Suppose that we have a set of N values:

{x₁, x₂, ..., xₙ}

The median is the value in the middle, and the mean is calculated as:

[tex]M = \frac{(x_1 + x_2 + x_3 ... + x_n)}{N}[/tex]

Because here we have "the median" then we will assume that N is odd, and there is only one median, the value "k"  (if N was even, the median would be the mean of the two middle values, that case is really similar to the case where N is odd, so solving only one of the cases is enough)

Now we add 7 to all the values greater than the median

We subtract 7 to all values smaller than the median.

Then the median remains unchanged (because we did not add nor subtract anything to the median).

The new mean will be:

[tex]M' = \frac{(x_1 - 7) + (x_2 - 7) + ... + (x_{k}) + ... + (x_n + 7)}{N} = \frac{(x_1 + x_2 + ... + x_n) + (-7)*(n/2 - 0.5) + 7*(n/2 - 0.5)}{N} = \frac{(x_1 + x_2 + ... + x_n)}{N} = M[/tex]

So the mean does not change.

Because the mean is computed as the sum of the numbers divided by N, and the mean does not change, and N does not change, then the sum of the numbers does not change.

Finally, the standard deviation is computed as:

[tex]SD = \sqrt{\frac{(x_1 - M)^2 + ... + (xn - M)^2}{N} }[/tex]

Because M does not change, if we add or subtract numbers to some of the values, the standard deviation will change (Because all the terms are squared, so the added and subtracted sevens don't cancel like in the previous cases)

Then the only value that does not have the same value in both the original and new data sets is the standard deviation.

Answer:

can you take another picture its blurry

Step-by-step explanation:

Answer:

7. 1520.53 cm²

8. 232.35 ft²

9. 706.86 m²

10. 4,156.32 mm²

11. 780.46 m²

12. 1,847.25 mi²

Step-by-step explanation:

Recall:

Surface area of sphere = 4πr²

Surface area of hemisphere = 2πr² + πr²

7. r = 11 cm

Plug in the value into the appropriate formula

Surface area of the sphere = 4*π*11² = 1520.53 cm² (nearest tenth)

8. r = ½(8.6) = 4.3 ft

Plug in the value into the appropriate formula

Surface area of the sphere = 4*π*4.3² = 232.35 ft² (nearest tenth)

9. r = ½(15) = 7.5 m

Surface area of the sphere = 4*π*7.5² = 706.86 m² (nearest tenth)

10. r = ½(42) = 21 mm

Plug in the value into the formula

Surface area of hemisphere = 2*π*21² + π*21² = 2,770.88 + 1,385.44

= 4,156.32 mm²

11. r = 9.1 m

Plug in the value into the formula

Surface area of hemisphere = 2*π*9.1² + π*9.1² = 520.31 + 260.15

= 780.46 m²

12. r = 14 mi

Plug in the value into the formula

Surface area of hemisphere = 2*π*14² + π*14² = 1,231.50 + 615.75

= 1,847.25 mi²
