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

Explanation:

Let's find the speed or rate of the car

distance = rate*time

rate = distance/time

rate = (275 miles)/(5 hours)

rate = 55 mph

If the bus traveled this same speed, and did so for 8 hours, then...

distance = rate*time

distance = (55 mph)*(8 hours)

distance = 440 miles

The measure of both complementary angle are 30 and 60 degrees.

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

In other words complimentary angles are angles that sum up to 90 degrees.

Therefore, the first angle is 30 degrees greater than the measure of the second angle.

Hence,

let

x = measure of the second angle

first angle = x + 30

Therefore,

x + x + 30 = 90

2x + 30 = 90

subtract 30 from both sides of the equation

2x + 30 = 90

2x + 30 - 30 = 90 - 30

2x = 60

divide both sides by 2

x = 60 / 2

x = 30

Therefore, the measure of both complementary angle are 30 and 60 degrees.

The solved inequality for r is r ≥ −21.75. Therefore, option C is the correct answer.

Given that, r/(-2.5) ≤ 8.7.

We need to solve the inequality for r.

Inequalities are mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Now, the given inequality can be solved as follows:

Here, multiply -2.5 on both sides of the inequality.

That is, r/(-2.5) × -2.5 ≤ 8.7 (-2.5)

⇒ r ≥ −21.75 (Inequality gets reversed when multiplied by negative integers)

The solved inequality for r is r ≥ −21.75. Therefore, option C is the correct answer.

The probability of of the order spelling MATH is 1/24.

Probability is the chance of happening something or the occurrence of something . We can also define the probability as the chance of occurring or the chance of selecting something from the total set of value. It is always ranges from 0 to 1 where 0 is minimum value and 1 is maximum value of probability.

Formula for probability is :

[tex]prabability(event) = \frac{Favourable \ outcomes}{Total \ outcomes}[/tex]

where, the total outcomes is the sample space of our given data or we can say the total number of values in the sample space.

In the question given,

The sample space is the different ways of arranging the letter which is equals to 4 factorial.

=> Sample space = 4! = 24

and the Favorable outcome is the word "MATH".

Thus, The probability is 1/24,  because out of 24 of them only one can spell math.

b. Take the square root of both sides

Solution :

Square root: In mathematics, a square root of a number x is a number y such that y2 = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x.[1] For example, 4 and −4 are square roots of 16, because 42 = (−4)2 = 16.

n2 = 16

The equation of the transformed function is g(x) = (x - 2)² - 3 or g(x) = x² - 4x + 1.

Consider this straightforward illustration: The parent function, denoted by the red curve, is f(x) = x².

Blue is used to color the graph of the converted function g(x). Finding the equation for the function g is our objective.

Now,

Reflection of f across the x-axis: this gives us the function of the graph as:

f₁( x ) = x²

Translation of f₁ by 2 units to the right across the x-axis: this gives us the second transformed function.

f₂( x ) = ( x − 2 )²

Translation of f₂ by 3 units up across the negative y-axis: this gives us the transformed function.

g(x) = ( x − 2 )² - 3 = x² - 4x + 4 - 3

g( x ) = x² - 4x + 1

Now, the points on the graph are ( 2, -3) and (0, 1).

Verifying the equation.

For ( 2, - 3),

g(2) = 2² - 4(2) + 1

g(2) = 4 - 8 - 1 = - 4 + 1 = - 3

For point ( 0, 1):

g(0) = 0² - 4(0) + 1

g(0) = 1

Hence the equation of the graph is g(x) = x² - 4x + 1.

9) X value range [-2/5,0] or [2,3]

b since I can't see a or c visablely) x>1

5) -5/3 ≤ x ≤ 2

6) The time interval by which the ball spends more than 1.5m above ground is about 0.263 <x< 1.166 seconds so about 1.397 seconds

9) To find the range of x value, you have to find the interception of these two solutions, and to do that, you have to find each of their solutions

To find the solution to 2x² ≥ 4x, you would first subtract 4x on both sides, resulting in 2x² - 4x ≥ 0. Then, you would factor to common terms, which are x and -2, the new inequality is 2x (x-2) ≥ 0. Then, you divide both 2x and 0 by 2. The new inequality is x (x-2) ≥ 0; you would then make everything ≥ 0. The solution is [- inf, 0] or [2, inf] for 5x² -13x -6 ≤ 0 you are basically doing the same thing for solving x which result in -2/5 ≤ x ≤ 3. With that said you find the interception of those 2 solutions which are [-2/5,0] and [2,3]. The first image should have a picture of the steps and a graph version of the work

b) To find the answer to x - 1/ (x+2) (x+3) > 0 you multiply both sides by (x+2) (x+3) you would then get x - 1 > 0. To islolate x you add 1 on both sides the final answer is x > 1

5) To solve 2x² + 3x + 1 ≤ 11x + 4x - x² you move 11x + 4x - x² on one side and simplify you would get 3x²

-x−10≤0. Then you split the second term into two terms which are 5x and -6x -> 3x² + 5 x - 6x - 10 ≤ 0 then you factor out the common terms in the terms you would then get (3x+5) (x-2) ≤ 0. Then you solve for x you would then get - 5/3 ≤ x ≤ 2. The new graph should show the solutions in graph form.

6) The first step is to create an inequality for the problem in this case it would be 7t - 4.9t > 1.5. At this point you move 1.5 on the left side to make 7t - 4.9t - 1.5 > 0 you would then multiply all terms on both sides by -1 to make -1.5 positive you would then get in standerd form 4.9t² -7t + 1.5 < 0. You would then factor with the quadratic formula after doing so you would get in its simplest form is (x - 1.166) (x - 0.263) < 0 then you would solve for x the time intervals that satisfy the scenario is about 0.263 ≤ x ≤ 1.166 then fine the difference between the solutions and that is about 1.937 seconds. The graph version is in the last picture.

The statement "When the sample means lies relatively far away from µ0 in a hypothesis test, the decision should be to reject the null hypothesis." is false

This is further explained below.

Generally, When the p-value is lower than or equal to your significance threshold, you should conclude that the null hypothesis is incorrect.

Your findings from the sample provide support to the alternative hypothesis, which indicates that the effect may be present in the population as a whole.

Remember, as a mnemonic device, that when the p-value is low, the null hypothesis must be discarded!
