Answer:

13

Step-by-step explanation:

By angle bisector property:

[tex] \frac{28}{49} = \frac{12}{2x + 7 - 12} \\ \\ \frac{4}{7} = \frac{12}{2x - 5} \\ \\ 4(2x - 5) = 12 \times 7 \\ \\ 8x - 20 = 84 \\ \\ 8x = 84 + 20 \\ \\ 8x = 104 \\ \\ x = \frac{104}{8} \\ \\ x = 13[/tex]

First let's review how to expand this!

(ax+b)^2=a^2*x^2+2abx+a^2

In this case

(2x^2+1/2)^2=2^2*x^2+2*1/2*2x+(1/2)^2

=4x^2+2x+1/4

Done!

Answer:

The third term of the sequence Tₙ = n² + 2n is:

T₃ = 15

Step-by-step explanation:

Given

As the sequence is given by

Tₙ = n² + 2n

To determine

The third term of the sequence

The third term of the sequence can be determined by substituting n = 3 in the sequence

Tₙ = n² + 2n

T₃ = (3)² + 2(3)

T₃ = 9 + 6

T₃ = 15

Therefore, the third term of the sequence Tₙ = n² + 2n is:

T₃ = 15

Answer:

A.) All the observations are the same value

Step-by-step explanation:

One of the statistical measures used to determine the spread or variability of a dataset is the variance or standard deviation. The standard deviation determines how a set of value varies about the mean value.

Mathematically,

Variability or spread = mean + number of standard deviations

Hence, a standard deviation of 0 ; means they there is no variability in the dataset. Hence, a standard deviation of 0 means all observations are of the same value.

For a set of data with a standard deviation of 0, the correct option is:

A: "All the observations are the same value."

For a given set {x₁, x₂, ...} with N elements.

With a mean M, we define the standard deviation as:

[tex]S= \sqrt{\frac{\sum (x_i - M)^2}{N - 1} }[/tex]

Notice that, because we have a squared element in the sum, all the elements of the sum are positive. So if we have a single value of the set that is different than the mean, then the standard deviation will be larger than zero.

Then the only case where the standard deviation is zero is the case where all the elements of the set are equal to the mean of the set, and that only happens if all the elements of the set are equal.

So the correct option is A:

"All the observations are the same value. "

Answer:

vertically Angle is correct answer

Answer:

no

Step-by-step explanation:

gravity is relevant to when something is being affected by the gravitational pull on earth, or any other planet. for example, i throw an apple into the air. and it comes back down, as newton said. what must come up, must come down. because of gravity, two objects being closer together does not affect the gravitational pull whatsoever. and the force of gravity doesn't change. as gravity just works on it's own, independent of the object, not dependent on the object. however certain objects will fall abit faster than others.

Answer: Each friend should pay $9.80

Step-by-step explanation: First add up all their checks, then divide them by 4 (4 because there 4 friends) to get the amount each friend needs to pay.

$12.20 + $11.00 + $8.50 + $7.50= $39.20

39.30 / 4 = $9.80

(a). The probability that one of these five numbers is 3 is [tex]\frac{5}{6}[/tex].

(b). The least possible sum of the five numbers​ is 15

Probability is the ratio of number of favourable outcomes to the total number of outcomes.

When a fair dice has six sides, numbered 1 to 6 ,After it is rolled, five of the numbers can be seen.

The probability that one of these five numbers is 3 is computed as,

                        [tex]P(E)=\frac{5}{6}[/tex]

The least possible sum of the five numbers, when the number 6 is hidden.

Least sum = 1 + 2 + 3 + 4 + 5 = 15

Have a wonderful day!

The experiment was not double-blind because volunteers were randomized into the two groups. The correct option is c.

A type of clinical experiment where neither the research team nor the subjects are aware of the treatment or intervention they are receiving until the trial is complete. As a result, the study's findings are less likely to be skewed.

Because neither the participant nor the clinician is aware of who has received what treatment, double-blind studies are regarded as the most trustworthy sort of research. This is done in an effort to lessen bias and the placebo effect.

Both the researchers and the test subjects must be uninformed of who is receiving the treatment and who is receiving a placebo in a double-blind trial.

Therefore, the correct option is c. volunteers were randomized into the two groups.

Answer:

360°

Step-by-step explanation:

Based on what I know that the total of degrees has to be 360°. So, two sides of the rhombus have to have two acute angles and two obtuse angles. So, the  Image shows that the 63° is an acute angle. So, multiply 63 by 2 which is 126. Then subtract 126 from 360 which is 234. Then, divide 234 by 2 which is 117. Lastly, add 63 with 63 and 117 with 117 which is 360.
