Answer: 5

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

First do 18-2 which is 16
Then do 16 divided by 8 which is 2

Right now the equation is 8 - 1 - 2

Then we minus 8 by 1 which is 7
and then 7 - 2 which is 5
So then our final answer is 5

Let x be the amount of money invested in the 9% fund. Then the amount invested in the stock is $32,000 - x. The profit from the 9% investment is 0.09x and the loss from the stock investment is -0.03(32000 - x).

What exactly does compounding mean?

Compounding is the method through which interest is added to both the principle balance already in place and the interest that has already been paid. Thus, compounding can be thought of as interest on interest, with the result that returns on interest are magnified over time, or the so-called "magic of compounding."

The overall net profit was $2,040, so we can set up the following equation to solve for x:

0.09x - 0.03(32000 - x) = 2040

Expanding the second term,

0.09x - 9600 + 0.03x = 2040

Combining like terms,

0.12x - 9600 = 2040

Adding 9600 to both sides,

0.12x = 1640 + 9600

Simplifying,

0.12x = 11240

Dividing both sides by 0.12,

x = 93, 666.67

So, the amount invested in the 9% fund is $93,666.67 and the amount invested in the stock is $32,000 - $93,666.67 = $-61,666.67.

Clothilde thinks that going to the circus costs her less than Naomie and she is right

What is an equation?

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.

Let the cost of 1 child be "c"

Let the cost of 1 adult be "a"

Given a=1.5c

Clothilde buys a ticket for her, for her

husband and for her 2 children.

=> She buys for 2 adults and 2 children

price = 2a+2c

Substitute  a=1.5c

price = 2(1.5c )+2c

        = 3c+2c

        = 5c

Naomie

buys tickets for her 4 children and herself.

=> She buys for 1 adult and 4 children

price = a+4c

Substitute  a=1.5c

price = 1.5c +4c

         = 5.5c

5c  < 5.5c

So, Clothilde thinks that going to the circus costs her less than Naomie and she is right

The average speed for the whole journey is 72.5 km/h. The result is obtained by using the formula for the average speed.

Average speed is the overall speed of a moving object during a given amount of time. It can be expressed as

Avg speed = Total distance covered / Total time taken

The speed itself is

v = s/t

Where

Orla drove 155 km in 2 hours. Then, she drove 48 km at a speed of 60 km/h. Find the average speed for the whole journey!

We have

The time taken in the second journey is

v₂ = s₂/t₂

60 = 48/t₂

t₂ = 48/60

t₂ = 0.8 h

The average speed will be

= total distance covered / total time taken

= (s₁ + s₂)/(t₁ + t₂)

= (155 + 48)/(2 + 0.8)

= (203)/(2.8)

= 72.5 km/h

Hence, the whole journey will have the average speed of 72.5 km/h.

The given trigonometric function Cosec 2A + cot 4A = cot A - cosec 4A​ can be proved using the properties of the trigonometric functions.

Simply put, trigonometric functions—also referred to as circular functions—are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.

Given that,

Cosec 2A + cot 4A = cot A - cosec 4A​

Taking the LHS

= Cosec 2A + cot 4A

= 1 / sin 2A + cos 4A / sin 4A

To take the LCM we multiply and divide the first term by 2cos 2A:

= 2cos 2A / 2 sin 2A cos 2A + cos 4A/ sin4A

= 2cos 2A / sin 4A + cos 4A/ sin4A

= 2 cos 2A + 2 cos² A -1 / Sin 4A

= 2 cos 2A (1 + cos 2A) - 1 / sin 4A - 1/ sin 4A

=  2cos 2A 2cos² A / 2 sin 2A cos 2A - cosec 4A

= cos A / sin A - cosec 4A

= cot A - cosec 4A

Hence proved.

Let's call the time you drove "x" and the time your wife drove "y". We know that the sum of the two times is 20 hours:

x + y = 20

We also know the distance traveled during each part of the trip. The first part of the trip was 55x miles, and the second part of the trip was 65y miles. The total distance of the trip was 1170 miles:

55x + 65y = 1170

We can use the first equation to solve for x in terms of y:

x = 20 - y

We can then substitute this expression for x in the second equation:

55(20 - y) + 65y = 1170

Simplifying and solving for y:

1100 - 55y + 65y = 1170

10y = 70

y = 7

So your wife drove for 7 hours. We can use the first equation to find your driving time:

x + 7 = 20

x = 13

So you drove for 13 hours.

Answer:

Step-by-step explanation:

The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:

Slope = (y2 - y1) / (x2 - x1)

Plugging in the given points, we get:

Slope = (9 - (-7)) / (7 - (-3))

= 16 / 10

= 1.6

So the slope of the line passing through (-3, -7) and (7, 9) is 1.6.

Answer:

m = 8/5

Step-by-step explanation:

Slope = rise/run or (y2 - y1) / (x2 - x1)

(-3,-7) and (7,9)

We see the y increase by 16 and the x increase by 10, so the slope is

m = 16/10 = 8/5

So, the slope is 8/5

8 posters

Explanation:

first you need to find how many he posted the first week. You do this by multiplying 72 by 1/3, or 72/3. That is 24. Then, you need to subtract that amount, 72-24 is 48. Then, you need to figure out how many he posted the second week. To do that, you need to figure out what 1/6 of 48 is first. So you would need to divide 48 by 6, which equals 8. So if John posted 5/6 of 48, you then need to multiply 8 by 5, equaling 40. If john posted 40 of his 48, then 48-40 is 8, meaning he has 8 posters to post.

Answer:

Step-by-step explanation:

a) The value of p, the population proportion of students in Mrs. Jones's AP Statistics class who got a 5 on the AP Statistics exam, is 3/5. This is because out of the 5 students, 3 (Ashley, Brayden, and Carmen) got a 5 on the AP Statistics exam.

b) The 10 possible simple random samples of size n = 2 are:

Ashley, Brayden; P = 2/2 = 1

Ashley, Carmen; P = 2/2 = 1

Ashley, Dale; P = 1/2 = 0.5

Ashley, Eve; P = 1/2 = 0.5

Brayden, Carmen; P = 2/2 = 1

Brayden, Dale; P = 1/2 = 0.5

Brayden, Eve; P = 1/2 = 0.5

Carmen, Dale; P = 1/2 = 0.5

Carmen, Eve; P = 1/2 = 0.5

Dale, Eve; P = 0/2 = 0

c) To create the dotplot for the sampling distribution of p:

Label the number line with 0, 0.5, 1

For each sample proportion calculated, place a dot above the corresponding value on the number line

Repeat this process for all sample proportions

d) Yes, the sample proportion is an unbiased estimator of the population proportion. This means that on average, the sample proportion will equal the population proportion. In other words, the mean of the sampling distribution of the sample proportion will equal the population proportion.

The volume of each marble in a 26 liter glass tank is 12.

The tank's volume is listed as 26.

The tank requires 20.9 liters of water to fill when 85 marbles are placed inside.

So the volume of 85 marble

= 26-20.9 = 5.1

So, volume of each marble

= 5.1/85 = 0.06

Therefore, the volume that will be covered if William wishes to use 200 marbles is:

200*0.6 = 12

Therefore, the volume of marbles in a 26 litre tank is equal to 12

Water will therefore be needed to fill the tank.
