You calculate the probability of an event and it turns out to be 0.7, you know

that [2]

A. the event is certainly going to happen.

B. the event is probably not going to happen.

C. the probability of it not happening is 0.3.

D. you made a mistake.

Answers

Answer 1

Answer:

C. the probability of it not happening is 0.3.

Step-by-step explanation:

Probability of event happening is of 0.7.

Either it happens, or it does not. The sum of these probabilities is 100%.

0.7 probability of happening, so 1 - 0.7 = 0.3 probability of not happening, and the correct answer is given by option C.

A is wrong as the probability is not 1, and B is wrong as the probability is higher than 0.5.

B. What was the highest temperature this month?

Step-by-step explanation:

Rory is recording the highest temperature for the duration of the day for month's worth of data.

B. is the easiest one to answer, as you simply will have to look for the greatest number within the set, and that will be the answer.

A. is too broad, and does not imply that only the "high temperature" is needed, rather just a leveled temperature within day in that month.

C. is the opposite of what Rory had recorded, and without data, he cannot answer it.

D. is answerable as well, but, again, the only temperature recorded is the high temperature. Temperature can fluctuate depending on the time of the day, and can be in the 50s one hour and the 90s in another.

a = (x - 5)(x + 8)

A local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful only if the average time spent on a delivery does not exceed 40 minutes. The owner has randomly selected 21 customers and delivered pizzas to their homes. What hypotheses should the owner test to demonstrate that the pizza delivery will not be successful

Answers

Answer:

H0 : u ≤ 40 mins  against  Ha: u> 40 mins

Step-by-step explanation:

The hypotheses will be set as follows

H0 : u ≤ 40 mins  against  Ha: u> 40 mins

The null hypothesis is that the mean delivery time is less and equal to 40 minutes.

against the claim

that the mean delivery time is greater than 40 minutes.

40 minutes is taken because the success depends on the factor that if the delivery time is less and equal to 40 minutes then the home delivery service will be successful

But if it is greater than 40 minutes then the home delivery service will not be successful

What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The value of sin C will be

sin C = 3 / 5

The value of sin D will be

sin D = 4 / 5

The value of cos C will be

cos C = 4 / 5

The value of cos D will be

cos D = 3 / 5

The value of tan C will be

tan C = 3 / 4

The value of tan D will be

tan D = 4 / 3

The product of sin D and cos D will be

sin D × cos D = (4 / 5) × (3 / 5)

sin D × cos D = 12 / 25

The product of tan C and tan D will be

tan C × tan D = (3 / 4) × (4 / 3)

tan C × tan D = 1

The product of cos C and tan D will be

cos C × tan D = (4 / 5) × (4 / 3)

cos C × tan D = 16 / 15

Then the matching will be given below.

12/25 = sin D × cos D3/5 = sin D16/15 = cos C × tan D4/5 = sin C

Find the range for the measures for the third side of a triangle with the given measures of two sides. 14 and 23

Answers

Given:

Two sides of a triangle are 14 and 23.

To find:

The angle for the measures for the third side of a triangle.

Solution:

If a, b, c are three sides of a triangle, then

[tex]a+b>c[/tex]

[tex]a+c>b[/tex]

[tex]b+c>a[/tex]

It is given that two sides of a triangle are 14 and 23.

Let the third side of the given triangle be c. Then, using the above inequalities, we get

[tex]a+b>c[/tex]

[tex]14+23>c[/tex]

[tex]37>c[/tex]                 ...(i)

Similarly,

[tex]a+c>b[/tex]

[tex]14+c>23[/tex]

[tex]c>23-14[/tex]

[tex]c>9[/tex]                 ...(ii)

And,

[tex]b+c>a[/tex]

[tex]23+c>14[/tex]

[tex]c>14-23[/tex]

[tex]c>-9[/tex]                 ...(iii)

Using (i), (ii) and (iii), we get

[tex]9<c<37[/tex]

Therefore, the range for third side of the triangle is [tex]9<c<37[/tex].

The table of values represent a linear function. Write an equation in slope-intercept form that represents the function.

Answers

Let's take the first value of x and y.

When x = 4, y = -3. This also gives us point

(4, -3). We need another point to find the slope.

From the table I see the point (5, -4.5)

.

See it?

Let m = slope

m = (-4.5 -(-3))/(5-4)

m = (-4.5 + 3)/1

m = (-1.5)/1

m = -1.5

Now, use the slope m and one of the points to plug into the point-slope formula.

Here is the point-slope formula:

y - y_1 = m(x - x_1)

I will use the point (4, -3) and m.

y - (-3) = -1.5(x - 4)

y + 3 = -1.5x + 6

The slope-intercept form we want is

y = mx + b.

y = -1.5x + 3

A student scored 82, 95, 90 and 87 on his first 4 tests. What would he
need to make on his 5th test to have an average 95.

Answers

Not gonna give an answer, sorry. Instead, I'll show you a similar example so you can be able to solve it.

An average test score is the sum of all the scores on an assessment divided by the number of test-takers.

For example, if three students took a test and received scores of 69, 87, and 92.

These numbers would be added together and then divided by three to get an average of 82.6.

I hope you know what to do now.

Answer:

Step-by-step explanation:

(82 + 95 + 90 + 87 + x) / 5 = 95          Add  like terms on the left

(354 + x) / 5 = 95                                 Multiply by 5

354 + x = 95 * 5

354 + x = 475                                      Subtract 354 from both sides

x = 475 - 354

x = 121

On the first step, you need to add an x which represents the score he needs. You divide by 5 because that's how many scores there and and the 5 gives you an average.

Answers

Answer:

the standard error is 153.125

Step-by-step explanation:

given that

The random sample is 256

The sample mean is $35,420

And, the standard deviation is $2,450

We need to find out the standard error

We know that

= standard deviation ÷ √random sample

= 2450 ÷ √256

= 2450 ÷ 16

= 153.125

Hence, the standard error is 153.125
