you invested money in two funds. last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you receive a total of $921. This year, the first fund paid a 10% dividend and the second only 1%, and you received a total of $846. How much money did you invest in each fund?​

Answers

Answer:

x= $ 7100 investment in first fund

10x+y=84600 substitute the value of x

10*7100+y=84600

Answers

Answer:

74 degrees

The angles are adjacent, since they have a common side (adjacent basically means right next to each other).

Step-by-step explanation:

Both angles are supplementary, since they add up to 180 (make a straight line together).

Scores of an IQ test have a​ bell-shaped distribution with a mean of and a standard deviation of . Use the empirical rule to determine the following. ​(a) What percentage of people has an IQ score between and ​? ​(b) What percentage of people has an IQ score less than or greater than ​? ​(c) What percentage of people has an IQ score greater than ​?

Answers

Complete question is;

Scores of an IQ test have a​ bell-shaped distribution with a mean of 100 and a standard deviation of 13. Use the empirical rule to determine the following.

​(a) What percentage of people has an IQ score between 87 and 113​?

​(b) What percentage of people has an IQ score less than 74 or greater than 126​? ​

(c) What percentage of people has an IQ score greater than 139​?

Answer:

A) 68% of the people had an IQ score between 87 and 113

B) 5% of the people had IQ scores less than 74 and greater than 126.

C) 0.15% had an IQ score greater than 139

Step-by-step explanation:

We are given;

Mean; x¯ = 100

Standard deviation; σ = 13

According to the empirical rule in statistics;

>> 68% of the data lies within one standard deviation of the mean

>> 95% of the data lies within two standard deviations of the mean

>> 99.7% of the data lies within three standard deviations

A) We want to find the percentage of people with an IQ score between 87 and 113.

Within one standard deviation, we have;

x¯ ± σ

>> (100 - 13), (100 + 13)

>> (87, 113) which is the range we are looking for.

Thus, 68% of the people had an IQ score between 87 and 113

B) we want to find percentage of people has an IQ score less than 74 or greater than 126.

Let's first find those who had between 74 and 126.

Let's use two standard deviations within the mean.

x¯ ± 2σ

>> (100 - (2×13)), (100 + (2×13))

>> (74, 126) which is the range we are looking for.

So percentage that have IQ scores between 74 and 126 is 95%

Thus;

Percentage of those who had less than 74 and greater than 126 is;

P = 1 - 95%

P = 5%

C) we want to find the percentage of people that had an IQ score greater than 139.

Let's use the z-score formula;

z = (x¯ - μ)/σ

z = (139 - 100)/13

z = 39/13

z = 3

This means it is 3 standard deviations above the mean.

Thus;

Since it's one side outside the mean, then;

Percentage of people with an IQ score greater than 139 = (1 - 99.7%)/2 = 0.3%/2 = 0.15%

jim began to bike a 173 mile bicycle trip to build up stamina for a for a triathlete competition.​ Unfortunately, his bicycle chain​ broke, so he finished the trip walking. The whole trip took 5 hours. If Jim walks at a rate of 4 miles per hour and rides at the rate of 38 miles per hour , find the amount of time he spent on the bicycle

Answers

Answer

3.5 hours

Step-by-step explanation:

Let us represent

The time spent walking as x

The time spent riding as y

Jim began a 146​-mile bicycle trip to build up stamina for a triathlete competition.​ Unfortunately, his bicycle chain​ broke, so he finished the trip walking. The whole trip took 5 hours.

Hence:

x + y = 5.... Equation 1

x = 5 - y

If Jim walks at a rate of 4 miles per hour and rides at 40 miles per​ hour,

The formula for Distance = Speed × time. Hence,

4 × x + 40 × y = 146 miles

4x + 40y = 146.... Equation 2

We substitute 5 - y for x in Equation 2

4(5 - y) + 40y = 146

20 - 4y + 40y = 146

Subtract 20 from both sides

20 - 20 - 4y + 40y = 146 - 20

- 4y + 40y = 146 - 20

36y = 126

y = 126/36

y = 3.5 hours

Since the time he spent raiding his bicycle is represented by "y", the amount of time he spent on the bicycle is 3.5 hours

-6 = -2a + 32

-32         -32

-38 = -2a

divide by -2

a = 19

Answer:

a=19

Step-by-step explanation:

-2(a+3) = -4a + 32

-2a - 6 = -4a + 32(Group like terms)

-2a+4a=32+6

2a=38(Divide both sides by 2)

A company found that the average customer rating of
a certain product can be used to estimate the total
income from that product, according to the equation
y= 44x+500, where y is the income,in dollars, and x is
the average customer rating. Which of the following
best describes the slope of the graph of the equation
in the xy-plane?
A) For every increase of 44 in the average customer rating,
the estimated increase in income is $500.
B) For every increase of 1 in the average customer rating,
the estimated increase in income is $544.
C) For every increase of 1 in the average customer rating,
the estimated increase in income is $500.
D) For every increase of 1 in the average customer rating,
the estimated increase in income is $44.

Answers

The option that best describes the slope of the graph of the equation in the xy-plane is: D) For every increase of 1 in the average customer rating, the estimated increase in income is $44.

The equation y = 44x + 500 represents the relationship between the average customer rating (x) and the estimated income (y) of a certain product. The coefficient of x, which is 44, determines the slope of the graph. In this case, it means that for every increase of 1 in the average customer rating, the estimated increase in income is $44. Therefore, option D is the correct answer. Option A is incorrect because it suggests a fixed increase of $500 for every increase of 44 in the rating, which is not accurate. Option B is also incorrect as it implies a higher increase in income than what the equation represents. Option C is incorrect because it overestimates the increase in income without considering the coefficient of x.

The length of x in the right triangle is 31.9 units.

How to solve the side of a right triangle?

A right triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

Therefore, the side of a right triangle can be found using trigonometric ratios as follows:

Hence,

cos 15° = adjacent / hypotenuse

adjacent side = x

hypotenuse side = 33 units

cos 15° = x / 33

cross multiply

x = 33 cos 15°

x = 33 × 0.96592582628

x = 31.8755522675

Therefore,

x = 31.9 units
