2. Sumara Kato's savings account has a balance of $1663. After 19 years, how much interest
will she have eamed if her rate is 5.5% compounded annually?

Answers

Answer:

Step-by-step explanation:

interest = Amount - principal

A = P(1+r)^t

r = 5.5% = 5.5/100 = 0.055

A = 1663(1+ 0.055)^19

A = 1663 (1.055)^19

A = 4,599.270812203411

Let’s say A = 4,599

interest = 4,599-1663 = 2,936

Find the slope and y-intercept of the graph of the linear equation.
12. y= 4x

Answers

Answer:

Slope = 4, y-intercept = (0,0)

Step-by-step explanation:

This problem is written in slope-intercept form. Meaning it is in the form y=mx+b. "M" is the slope, and "B" is the y-intercept. With that information, we easily see that 4 is the slope of the graph (it will go up 4 points for everyone one point it goes right). It seems that there is no y-intercept though, that is because we are expected to know that y=4x is the same as y=4x+0. Meaning, the problem can also be written this way and the y-intercept must be 0.

The radius of a cylindrical water tank is4.5ft , and its height is12ft . What is the volume of the tank? Use the value for , and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.

Answers

Answer:

[tex]763 ft^3[/tex] or 763 cubic feet.

Step-by-step explanation:

The tank is cylindrical and the volume of a cylinder is given as:

[tex]V = \pi r^2h[/tex]

where r = radius and h = height

The radius, r, of the tank is 4.5 ft and the height, h, of the tank is 12 ft.

Therefore, the volume of the cylindrical water tank is:

[tex]V = \pi * 4.5^2 * 12\\V = 763.407 ft^3[/tex]

Approximating to whole number, the volume of the tank is [tex]763 ft^3[/tex] or 763 cubic feet.

a, b , c and d are four integers.
their mean is 8.
their mode is 7.
their median is 7.5.
find the four integers

Answers

7, 7, 8, 10 are the four integers

Explanation:
7 + 7 + 8 + 10 = 14 + 18 = 32 / 4 (to find mean) = 8

Mode means a number that occurs the most often, so 7 will be the answer

Median is the middle number, and that will be 7 and 8. To find median, you add up 7 and 8 together and divide the number by 2 to find the average, and that will be 7.5

The four integers are 7, 7, 8, 10

What are the integers ?

Four integers are a, b, c, d

Mean = Sum of integers/Total number of integers

         = (a+b+c+d)/4

According to the question,

Mean = 8

i.e. (a+b+c+d)/4 = 8

⇒ a+b+c+d = 32 ......(1)

Median (for even no. of integers) = ([tex]\frac{n}{2}^{th} +(\frac{n}{2}+1)^{th}[/tex] term)/2

                                                       = (2nd+3rd term)/2

                                                       = (b+c)/2

According to the question,

Median = 7.5

i.e. (b+c)/2 = 7.5

⇒ b+c = 15  .....(2)

We know that, most frequent data is the mode.

So, mode = 7 means the number 7 occurs most frequently.

7 is not more than 2 times, because if 7 occurs 3 times, then 2nd & 3rd term will be 7 & median will be (7+7)/2 i.e. 7, so 3rd term must be larger than 7 to adjust the median value, which is 7.5

Then 1st two integers are 7 & 7

i.e. a = b = 7

Now, from (2), b+c = 15  

                    ⇒ 7+c=15

                    ⇒ c =15-7

                    ⇒ c = 8

Now, from (1) we get, a+b+c+d = 32

                                 ⇒ 7+7+8+d = 32

                                 ⇒ 22+d = 32

                                 ⇒ d = 32-22

                                 ⇒ d = 10

So, a = 7, b = 7, c = 8, d = 10

What is the value of x?

Answers

Answer: x = 9, y = 5

Step-by-step explanation:

If all of the sides are equal, it is an equilateral triangle. Equilateral triangles are also equiangular. The angles of a triangle add up to 180 degrees, so each angle must equal 60 degrees.

set the equation equal to 60 to solve for x

7x - 3 = 60

add three to both sides

7x = 63

divide both sides by 7

x = 9

find y by setting the equation equal to 60

11y + 5 = 60

subtract 5 from each side

11y = 55

divide both sides by 11

y = 5

Answer:

AC =3.76

Step-by-step explanation:

sin theta = opposite / hypotenuse

sin 70 = ? / 4

Multiply each side by 4

4 sin 70 = ?

3.758770783 = ?

Rounding to nearest hundredth

3.76 = ?

AC =3.76

Answer:

3.76 units

Step-by-step explanation:

We want to use trigonometry to solve this - specifically, the trigonometric function sine, which is opposite divided by hypotenuse.

Here, the opposite side is AC, which is what we want to find, while the hypotenuse is AB, which is 4. The angle itself is angle ABC, which is 70 degrees. Now, write:

sin(70) = opposite / hypotenuse = AC / 4

Multiply both sides by 4:

AC = 4 * sin(70) ≈ 3.76 units

Find the percent of all values in a normal distribution for which z ≤ 1.00, to the nearest tenth of percent.

Answers

Answer:

84.1% of all values in a normal distribution have z ≤ 1.00.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

The percent of all values in a normal distribution for which z ≤ 1.00.

This is the pvalue of Z = 1.

Z = 1 has a pvalue of 0.8413.

Converting to percentage, to the nearest tenth.

84.1% of all values in a normal distribution have z ≤ 1.00.

You randomly survey men and women about whether they plan to watch a football game on Sunday afternoon. A total of 40 men plan to watch a football game and a total of 17 women do not plan to watch a football game. A total of 45 women are surveyed. A total of 33 people do not plan to watch a football game. How many people did you survey?

Answers

Answer: 101

Step-by-step explanation:

45 women total

17 women will not watch the game

So 33 people did not want to watch the game and 17 are women

33-17 = 16 men who won’t watch the game

So 40 men who will and 16 men who won’t equals 56 men and 45 women

56+45= 101

If P(A)=35, P(B)=13, and P(A∩B)=18, are A and B independent?

Select the option that provides both the correct answer and the correct reason.

No, because 35(13)≠18.

Yes, because 35(13)=18.

Yes, because 35+13=18.

No, because 35÷13≠18.

No, because 35+13≠18.

Answers

Answer:

P(A) x P(B) = 35 x 13 = 455

P(A∩B) = 18

=> P(A) x P(B) ≠ P(A∩B).

=> A and B are not independent.

=> Option A (No, because 35(13)≠18) is correct.

Hope this helps!

:)

A and B are not independent because 35(13)≠18), the correct option is A

What is the independent probability?

Independent events and probability can be defined as those occurrences that are not dependent on any specific event.

P(A)=35, P(B)=13, and P(A∩B)=18, are A and B independent.

It is to note here that A and B are the odd number outcome and multiples of 3 respectively. So, P (A ∩ B) = 18

P(D│E) = P (D ∩ E)/ P(B)

P(D│E) = 18/13

Here P(D) = P(D│E) = 18/13, which entails that the occurrence of event E will not be affected by the probability of event D’s occurrence.

Taking A and B as independent events, then P(D│E) = P(D).

Here, A and B are not independent because 35(13)≠18), the correct option is A.
