find the value of x. ​

Answer:

An =4^(n-1)

Step-by-step explanation:

hello :

the sequence is geometric because : (-64)/(-16) = (-16)/(-4)=-4/-1= 4=r

the nth term is :  An =A1 × r^(n-1)

a common ratio is : r  and A1 the first term

in this exercice :   r =4        A1 = 1

An =A1 × r^(n-1)

An =1 × 4^(n-1)=4^(n-1)

The Sum of 2 Numbers is 17 & Their Product is 70. Find the Numbers -

Step-by-step explanation:

The Factors of 70 are - 1, 2, 5, 7, 10, 14, 35 & 70

Now, Find the two Factors, when added gives the Sum as 10 & the Product of Multiplication as 17 -

From the given Statement, we can see that when the Factors 7 & 10, when Added gives the Sum as 17 and Their Product as 70 *(7 + 10 = 17 ; 7 × 10 = 70)

Therefore, the two Numbers are 7 & 10

Answer:

6 units

Step-by-step explanation:

they are six units apart just count the amount of units they are from each other or since they are in the same quadrant and y-axis just subtract the 10 from the 4

Answer:

6 units is the answer.

Step-by-step explanation:

points are (10,-5) and (4,-5)

Pythagorean theorem can be written as,

[tex]d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{(4-10)^2 + (-5-(-5))^2}\\\\d=\sqrt{(-6\\)^2+(0)^2} \\\\d=\sqrt{36} \\\\d=6} \\\\[/tex]

∴ d = 6 units

Answer:

12 ft

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle θ = 41.5°

Opposite = 8 ft

Length of handrail =?

We can obtain the length of the handrail by calculating the Hypothenus. This can be obtained as follow:

Angle θ = 41.5°

Opposite = 8 ft

Hypothenus =?

Sine θ = Opposite /Hypothenus

Sine 41.5 = 8 / Hypothenus

0.6626 = 8 / Hypothenus

Cross multiply

0.6626 × Hypothenus = 8

Divide both side by 0.6626

Hypothenus = 8 / 0.6626

Hypothenus = 12 ft

Thus, the Lenght of the handrail is 12 ft

It would be the first one.

Step-by-step explanation:

the Twins are the same age. all three ages are 42 so it's the sum. if you were to find the age of the sisters you would minus 12 from 42 but that's not what it is here. so baisicly what it is, is [tex]42=s+s+12\\42=2s+12[/tex]

Answer:

Step-by-step explanation:

154 scholars chose to go to the amusement park.

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the number of scholars who chose to go to the amusement park and y represent the number of scholars who chose to go to the zoo.

scholars who chose to go to the amusement park is 140% of the number of scholars who chose to go to the zoo. Hence:

x = 140% of y = 1.4y

Also, There are 264 scholars in the sixth grade, hence:

x + y = 264

1.4y + y = 264

y = 110

x = 1.4(110) = 154

154 scholars chose to go to the amusement park.

pH = 6.1

Step-by-step explanation:

pH = -log[H]

pH = -log[8.1 x 10^-7]

pH ≈ 6.09

Therefore, option a, 6.1, is closest to this value and is the correct answer.

Answer:

Most people found the probability of just stopping at the first light and the probability of just stopping at the second light and added them together. I'm just going to show another valid way to solve this problem. You can solve these kinds of problems whichever way you prefer.

There are three possibilities we need to consider:

Being stopped at both lights

Being stopped at neither light

Being stopped at exactly one light

The sum of the probabilities of all of the events has to be 1 because there is a 100% chance that one of these possibilities has to occur, so the probability of being stopped at exactly one light is 1 minus the probability of being stopped at both lights minus the probability of being stopped at neither.

Because the lights are independent, the probability of being stopped at both lights is just the probability of being stopped at the first light times the probability of being stopped at the second light. (0.4)(0.7) = 0.28

The probability of being stopped at neither is the probability of not being stopped at the first light, which is 1-0.4 or 0.6, times the probability of not being stopped at the second light, which is 1-0.7 or 0.3. (0.6)(0.3) = 0.18

Answer:

  C)  4

Step-by-step explanation:

We observe that the top segments are in the same 3:4 ratio as the bottom segments. This means they are the same lengths: 3x = 12, 4x = 16. Either of these equations tells us x = 4.

_____

Additional comment

In case you aren't convinced, you can solve this using the secant rule for segments and circles: the product of the lengths to the circle intercepts are the same for both secants.

  12(12 +16) = 3x(3x +4x)

  336 = 21x² . . . . . simplify

Answer:

The point has a high leverage

Step-by-step explanation:

The point has a high leverage as it would act as an infinitesimal point that will have a very huge/drastic  impact on the fit of the model, and this impact can be seen in such ways as listed below :

removing this point will eliminate these drastic impact and make the correlation to be better.

From the information given about the outliner, the given point is not influential and therefore does not have high leverage.

An outlier refers to a data point whose response does not follow the general trend of the rest of the data.

A data point has high leverage if it has an extreme predictor x value. Here, x = 53 and, y = 28.5.

X is not an extreme point, the data point is not high leverage but an outlier. The data point doesn't follow the general trend of the rest of the data.

Hence the given point is not influential.
