How long will it take the population of a certain country to double if it’s annual growth rate is 7.3%?

Answers

Answer 1
9.5 years. The reason being you need to use the formula P(t)= P e kt in which you would get 2= 0.073t

Then you would write the equation as ln(2)= 0.073t

After you put the number on the same side and get t= ln(2)/ 0.073

And then you get and answer of 9.49 year which would round up to 9.5

Suppose you are making a sail in the shape of a right triangle for a sailboat. The length of the longest side of the sail is 65 ft. The sail is to be 63 ft high. What is the length, in feet, of the third side of the sail?

Answers

Answer:

in right angled triangle ABC

hypotenuse [h]=65ft

base[b]=xft

height[p]=63ft

by using Pythagoras law

h²=p²+b²

65²=63²+x²

x²=65²-63²

x=√256

x=16feet

so the third side of the sail is 16ft.

Perpendicular=P=63Hypotenuse=H=65

Base:-

√H²-P²√65²-63²√16²16ft

Answer:

x= 33

Step-by-step explanation:

The sum of the angles on a straight line is 180°. This is abbreviated as 'adj. ∠s on a str. line'.

104° +x° +(x +10)°= 180°

2x° +114°= 180°

2x°= 180° -114°

2x°= 66°

Divide both sides by 2:

x°= 66° ÷2

x°= 33°

x= 33

A random sample of size 32 is selected from population X, and a random sample of size 43 is selected from population Y. A 90 percent confidence interval to estimate the difference in means is given as (−1.25,0.87)
.

Consider a change in the sample sizes such that a random sample of size 52 is selected from population X and a random sample of size 63 is selected from population Y. When all other things remain the same, what effect would such a change have on the interval?

Answers

Answer:

The level of confidence will increase.

Step-by-step explanation:

Could be wrong

The change in the sample size will lead to a decrease in the width of the interval.

What is a sample size?

A sample size simply means the number of subjects that are taken from the population for research.

In this case, increasing the sample size will decrease the standard error and therefore, the width of the confidence interval will reduce.

Therefore, as the sample size increases, the interval reduces.

How do I find the point of intersection?

Answers

Answer:

(-1 3/5, 2 3/5)

Step-by-step explanation:

Red Line:

m = 3-(-1)/-2-2 = 4/-4 = -1

b = 1

equation:  y = -x + 1

Blue Line:

m = 5-1/2-(-4) = 4/6 = 2/3

find 'b':

5 = 2(2/3) + b

15/3 = 4/3 + b

b = 11/3

equation:  y = 2/3x + 11/3

Find Point of Intersection:

-x + 1 = 2/3x + 11/3

multiply each side by 3 to get:

-3x + 3 = 2x + 11

-5x = 8

x = -8/5

find 'y':

y = -(-8/5) + 1

y = 8/5 + 1 = 13/5

y = 2 3/5

Suppose that an individual has a body fat percentage of 19.3% and weighs 187 pounds. How many pounds of her weight is made up of fat? Round your answer
to the nearest tenth.

Answers

Answer:

The individual has 36.09 pounds of body fat.

Step-by-step explanation:

Given that an individual has a body fat percentage of 19.3% and weighs 187 pounds, to determine how many pounds of her weight is made up of fat the following calculation must be performed:

(187 x 19.3) / 100 = X

3.609.1 / 100 = X

36.091 = X

Therefore, the individual has 36.09 pounds of body fat.

need help, I'm stuck on this​

Answers

Answer:

The answer is 729/64.

Step-by-step explanation:

I would first simplify the equation.

In the denominator, you can get rid of b^0 because that just equals 1.

For the a's in the numerator and denominator, you have to flip them so the exponents can be positive.

Equation:  [tex](\frac{3ab^2}{2a^3})^2[/tex]

Now, you can subtract a and a^3.  This would be 1/a^2.

Equation: [tex](\frac{3b^2}{2a^2})^2[/tex]

Now, you can square the whole equation.

Equation: [tex]\frac{9b^4}{4a^4}[/tex]

This is the simplified equation.  Now you can plug in -2 and -3.

Equation: [tex]\frac{9(-3)^4}{4(-2)^4}[/tex]

Equation: [tex]\frac{9(81)}{4(16)}[/tex]

What is the difference between an inscribed angle and a central angle?

Answers

Answer/Step-by-step explanation:

An inscribed angle is an angle that is formed by two chords in a circle. The vertex of an inscribed angle is at any point on the circumference of the circle.

On the other hand, a central angle is an angle that is formed by two radii of a circle. The vertex of a central angle is at the centerbof a circle.

Thus, from the diagram attached below, <EFG is an inscribed angle while <EOG is the central angle of the circle O.

Inscribed angle = ½ of the central angle.

A baker has three different recipes. Recipe A uses 3 cups of flour to make 12 rolls. Recipe B uses 5 cups of flour to make 24 rolls. Recipe C uses 11 cups of flour to make 48 rolls. Which recipe uses the most cups of flour per roll?

a) Recipe A
b) Recipe B
c) Recipe C
d) The ratios are all proportional

Answers

Answer:

Recipe A

Step-by-step explanation:

Hope this helped!!!

Answer:

[tex]{\huge\red{\fbox{{࿐αɴѕωєя࿐}}}}[/tex]

Recipe A:

Cups of flour used = 3

Rolls made = 12

Cups of flour per roll

[tex] = \frac{3}{12} \\ = \frac{1}{4} \\ = 0.25[/tex]

Recipe B:

Cups of flour used = 5

Rolls made = 24

Cups of flour per roll

[tex] \frac{5}{24} \\ = 0.20[/tex]

Recipe C:

Cups of flour used = 11

Rolls made = 48

Cups of flour per roll

[tex] \frac{11}{48} \\ = 0.22[/tex]

Now compare Recipe A, B & C.

[tex]0.25 > 0.22 > 0.20[/tex]

Recipe A > Recipe C > Recipe B.

✏ So, Recipe A used the most cups of flour per roll (option a).
