Multiply each side of the equation by -4/3 to clear the fraction

-4/3 *-3/4 (x+2) = 6*-4/3

1.24•10^3 + 2.3 • 10^4

Answers

The numbers in this addition problem are given in scientific notation. First we should convert these values into decimal notation by moving the decimal points over by the power of 10 that the significant figures are being multiplied by.

The first number is being multiplied by 10^3, so the decimal place will move to the right 3 places to become 1240.

The second number is being multiplied by 10^4, so it becomes 23000.

Add these together to get:

1240 + 23000 = 24240

The answer is 24240.

Answer:

the answer is c

Step-by-step explanation:

Probability is the ratio of the favorable event to the total number of events. Then P(A|B) is 0.40.

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

This Venn diagram shows sports played by 10 students.

Let event A = The students play basketball.

Let event B = The student plays soccer.

Then the probability of the will be

[tex]\rm P(A|B) = \dfrac{P(A \cap B)}{P(B)}\\\\\\P(A|B) = \dfrac{\dfrac{2}{10}}{\dfrac{5}{10}}\\\\\\P(A|B) = \dfrac{2}{5} = 0.40[/tex]

Thus, P(A|B) is 0.40.

What conjecture can you make about the sum of the first 22 positive even numbers?
A.) The sum of the product of the number of terms and the number of terms plus one.
B.) The sum is the product of the number of terms and the number of terms minus one.
C.) The sum is the product of the number of terms and two.
D.) The sum is equal to the number of terms squared.

Answers

Answer:

A.) The sum of the product of the number of terms and the number of terms plus one.

Step-by-step explanation:

So, we have the sum of the first 22 positive even numbers:

S = 2 + 4+ 6 + ... + 44

We know the sum of such sequence is given by the (sum of the first number (2) and the last number (44)) multiplied by the number of terms (11).

S = (2 + 44) * 11 = 46 * 11 = 506

Answer A tells us it should be the sum of the number of terms (22) by the number of terms plus one (22 + 1 = 23).

S = 22 * 23 = 506

That's confirmed.

Answer B would give 22 * 21 = 462, so it's not right

Answer C would give 22 * 2 = 44, obviously not right

Answer D would give 22 * 22 = 484, close but not right.

Answers

Answer:

pi*486mm ^3

Step-by-step explanation:

The equation of a hemisphere is half of that of a sphere, therefore it is 2/3pi*radius^3

We must calculate radius, which is just diameter/2 so 18/2 or 9

We can remove pi, as you want this measured in pi cubic millimeters.

this leaves us with (2/3)*9^3 which is 486cm

Henceforth, the final answer is pi*486 cubic millimeters.

Parking Lot A has twice as many cars as Parking Lot B. After 10 cars draw away from Parking lot A, and 13 cars moved from parking lot A to Parking lot B, Parking lots have the same amount of cars. How many cars were there in each Parking Lot?

Answers

Answer:

The original number of cars in parking Lot A was 72 cars and the original number of cars in parking Lot B was 36 cars

Step-by-step explanation:

Let

x----> original number of cars in parking Lot A

y----> original number of cars in parking Lot B

we know that

x=2y ----> equation A

(x-10-13)=y+13 ----> equation B

substitute equation A in equation B and solve for y

(2y-10-13)=y+13

(2y-23)=y+13

2y-y=13+23

y=36 cars

Find the value of x

x=2y -----> x=2(36)=72 cars

therefore

The original number of cars in parking Lot A was 72 cars

The original number of cars in parking Lot B was 36 cars

Parking Lot B initially had 36 cars, and Parking Lot A had twice that amount, which is 72 cars. After 10 cars left Parking Lot A, and 13 cars were transferred from Parking Lot A to B, both lots ended up with the same number of cars.

The question asks us to solve a word problem involving the principle of algebraic equations to determine the number of cars in two parking lots. Let's refer to the number of cars in Parking Lot B as x. Therefore, Parking Lot A has 2x cars since it has twice as many cars as Parking Lot B.

According to the problem, after 10 cars leave Parking Lot A and 13 cars move from A to B, both lots end up with the same number of cars. We can set up the following equation to represent this scenario:

Initial condition: A has 2x cars, B has x cars.

10 cars leave A: A now has 2x - 10 cars.

13 cars move from A to B: A now has (2x - 10 - 13) cars, and B now has (x + 13) cars.

Both lots have the same number of cars: 2x - 10 - 13 = x + 13.

Solving the equation:

2x - 23 = x + 13

2x - x = 13 + 23

x = 36

Therefore, Parking Lot B initially had 36 cars, and Parking Lot A had 72 cars (2×36).

The speed limit on a road is 45 mph. You want to clock the speed of a random sample of cars to test the hypothesis that the average speed of cars is greater than the speed limit. What kind of test would you use?

A left tailed test
A right tailed test
A two tailed test

The answer is a right tailed but I don't know why someone please explain

Answers

Answer:

A right tailed test

Step-by-step explanation:

In hypothesis testing there are two types of hypotheses;

The null hypothesis, H0 and the alternative hypothesis, Ha. The null hypothesis is the hypothesis of no difference and as such it always has an equality sign;

=, ≤, ≥

On the other hand the alternative hypothesis complements the null hypothesis meaning that if the null hypothesis is rejected then we take the alternative hypothesis to be true.

The kind of test to be carried out in hypothesis testing emanates from the inequality sign of the alternative hypothesis. The following are the key points to note, if the alternative hypothesis contains;

≠, then this automatically becomes a two tailed test

<, then this automatically becomes a left tailed test since the inequality sign is pointing towards the left.

>, then this automatically becomes a right tailed test since the inequality sign is pointing towards the right.

In the scenario given the following will be the set of hypotheses to be tested;

H0: u ≤ 45

Ha: u > 45 ( the hypothesis that the average speed of cars is greater than the speed limit)

The kind of test to be used is thus a right tailed test since the alternative hypothesis contains >.

I hope this will help.

Step-by-step explanation: I'm taking this test rn and it's C. K12 anyone?

Answer:

C.

Step-by-step explanation:

In the given graph, we have an isosceles triangles, which height divides its side in two equal parts.

So, from the division, we have to equal right triangles, which on leg is 6, and its angle is 80°, being the height the other leg.

Now, to find the height, we have to use trigonometric reasons, specifically, the tangent reasons because involves a relation with both legs

[tex]tan80=\frac{h}{6}[/tex]

So, we isolate [tex]h[/tex] to find its expression

[tex]h=6(tan80)[/tex]

If we compare with given choices, you'll observe that option C is the right answer.

There are no factors of -1 that sums to 2.

This trinomial cannot be factored.

Lee's trinomial:

[tex] {x}^{2} + 2x - 3[/tex]

There are factors of -3 that sums up to 2

An area is calculated by multiplying two dimensions (so answers A and D are not it).

Best solution is to divide the area into two large rectangles then ADD them together to get the total area.

Answers

Answer:

The last option choice [(1,3), (2,6), (3,9), (4,12)

Step-by-step explanation:

The key idea to understand in a function/relation is that each input can only have one output. Inputs are your x-variables and outputs are your y-variables.

In the first relation, you see the two points (3,4) and (3,5). 3 is your input [since its x] , however, it gives you two outputs [y's], 4 and 5. So you can cross out the first option.

In the second relation, look at the points (3,4) and (3,3). Again, both have the same input 3, but different outputs, 4 and 3. So you can cross out the second option.

In the third relation, look at all of the points. They all share a common input, 1, but different outputs, 2, 3, 4, and 5. So you can cross out the third option too.

Lastly, look at the last relation. They all have different inputs but the key thing to look at here is that each input only has one corresponding output. Thus, this is the right answer.
