Choose all answers that apply:
5x + 5 = -4.0-5
4x + 5 = -435
- 4x + 5 = - 48 - 4
- 4x + 5 = – 4x – 5

Answer:

[tex]x \ge 5[/tex] and [tex]x \ne -7[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \frac{\sqrt{x - 5}}{x + 7}[/tex]

Required

The domain

Set the denominator to not equal to 0

[tex]x + 7 \ne 0[/tex]

[tex]x \ne -7[/tex]

Also, the expression in roots must be 0 or positive i.e

[tex]x - 5 \ge 0[/tex]

[tex]x \ge 0+5[/tex]

[tex]x \ge 5[/tex]

Hence, the domain is defined for:

[tex]x \ge 5[/tex] and [tex]x \ne -7[/tex]

Answer:

a.The estimate is 43/60

b.No, he should not change the estimate based on this information

Step-by-step explanation:

The estimate he would make is dividing the number of bricks which he sees as green by the total number of bricks. That would be the probability of selecting a green brick out of all the 60 bricks.

Mathematically this probability is 43/60

No, Andre should not change his estimate.

The reason is that we are only told that she looked in the bag and saw 6 bricks, we do not know whether the kind of bricks he saw were green in color. The only time it is necessary for Andre to change his estimate is when it is confirmed that the six bricks seen by Mai in the bag were essentially confirmed to be green. without this confirmation, the estimate should not be changed.

Answer:

35

Step-by-step explanation:

So, lets go over what we know.

One side length is 28.

The other side length is 21.

The missing hypotenuse(longest length) is x.

We can use the pythagreons theorm to find x:

A^2+B^2=C^2. Remember that the two smaller side lengths are A and B, while the longest side length(in this case x) is C.

Plugging in our values:

28^2+21^2=x^2

Distrubute the ^2:

784+441=x^2

Combine the two side lengths:

1225=x^2

Now square root both sides to get x^2 alone(as x)

35=x

So our missing side length, x, is 35!

Hope this helps! :D

Answer:

Mrs. Hanson should order about 2.5 times as many crew neck shirts as raglan shirts.

Step-by-step explanation:

Answer:

Solution given:

principal [P]=P

time [T]=4 years

Rate [R]=13%

compound amount=18900

Simple interest=P-18900

we have

simple interest=[tex] \frac{P*T*R}{100} [/tex]

P-18900=[tex] \frac{P*4*13}{100} [/tex]

100P-1890000=52P

48P=1890000

P=1890000/48

P=39375

the sum that amounts =Rs 39375

b) H0:μ=90, H1:μ≠90

Step-by-step explanation:

The corporation wants to know if the mean number of days is different from the 90 days claimed.

This means that at the null hypothesis, we test if the mean number is the claimed value of 90, and so:

[tex]H_0: \mu = 90[/tex]

The corporations wants to know if the mean number is different, and thus, at the alternate hypothesis, we test if the mean number is different from 90, that is:

[tex]H_1: \mu \neq 90[/tex]

This means that the correct answer is given by option b.

Supposed to be next Thursday but I get off this week since I finished half of my classes already.

Answer:

Next Friday so...May 28th

Step-by-step explanation:

Answer:

a. Semester 1: 86.8, Semester 2: 87

b. Semester 1: 5.7, Semester 2: 6.3

c. Semester 1 because the standard deviation of the first semester was lower than of the second. This shows that his scores were closer to the mean and therefore he was more consistent.

Step-by-step explanation: Find the mean by taking the sum of the values for each semester and divide that sum by the number of values to find the average. Do this for both semesters. Now, find the absolute value of the difference between the mean and each value of the corresponding data set. Square each if those differences and sum them up. Now divide that sum by the number of data values and take the square root. This number is your standard deviation. You will use the standard deviations to make the comparison for part c. I hope this makes sense and helps!!!!

Answer:

No, Ben is not right.

Step-by-step explanation:

If we check the sequence of the numbers given, we can find that all of them is the odd multiple of the number three, i.e,

3,9,15,21,27.......

=> 3 (1,3,5,7,9......)

But 150 divided by 3 gives, 50, which is not an odd number, therefore, it will not come in this sequence.

Hope you understand.

Please mark it as the brainliest.

Thank You

No, Ben is not right. there is no term in the given sequence with a value of 150.

The difference between every two successive terms in an arithmetic series is always the same. The number "a" is the first term, and "d" is the common difference between the sequence. The nth term of an arithmetic sequence is given by. aₙ = a + (n – 1)d

The sequence given is an arithmetic sequence with a common difference of 6 since each term is 6 more than the previous one.

To find out if 150 is a term in the sequence, we can use the formula for the nth term of an arithmetic sequence:

aₙ = a₁ + (n - 1)d

where an is the nth term, a₁ is the first term, n is the number of the term we want to find, and d is the common difference.

Plugging in the values we know:

a₁ = 3

d = 6

To find n, we can use:

aₙ = 150

So, we have:

150 = 3 + (n - 1)(6)

Simplifying:

147 = 6n - 6

153 = 6n

n = 25.5

Since n is not a whole number, 150 is not a term in the sequence.

Answer:

Average Rate of change = 2

Step-by-step explanation:

Given - A rabbit hops 8 meters in one second. After 7 seconds, the rabbit has hopped 20 meters.

To find - What is the rabbit's average rate of change?

Formula used -

Average rate of change of a function f(x) in an interval [a, b] is [tex]\frac{f(b) - f(a)}{b - a}[/tex]

Proof -

Given that,

In 1 second - Rabbit hoops 8 meters

In 7 seconds - Rabbit hoops 20 meters

So,

Average Rate of change = [tex]\frac{20 - 8}{7 - 1}[/tex]

                                         = [tex]\frac{12}{6}[/tex]

                                         = 2

⇒Average Rate of change = 2

Answer:

x = 88

Step-by-step explanation:

Becuase this is a quadrilateral,  the opposite angles total 180 degrees. So, the opposite of x is 92. That would mean that x + 92 = 180. We subtract 92 from both non-variable sides to get the x by itself. 180 - 92 = 88. 92 - 92 = 0. this leaves us with X = 88

Step-by-step explanation:

Answer:

Step-by-step explanation:

Chords having equal measures are equidistant from the center of the circle.

Since, VW = XY

Therefore, ZP = ZR = 15 units

A perpendicular line drawn from the center of a circle to the chord is the bisector of the chord.

VR = WR = 20 units

By applying Pythagoras theorem in ΔZRV,

ZV² = ZR² + VR²

ZV² = (15)² + (20)²

ZV = √(225 + 400)

ZV = √625

ZV = 25 units

Therefore, measure of radius ZV = 25 units.

VW = XY [Given]

Therefore, XY = 2(20)

                        = 40 units
