Haven’t done geometry in a good while

Answer:

a = 0.3

b = 0.4

c = 40%

d = 15%

Step-by-step explanation:

There are a total of 10 tick marks. So we know that 1 tick mark = 10%

a has 3 tick marks so you can say it's 0.3

b has 4 tick marks so you can say it's 0.4

c also has 4 tick marks, but it's asking for the percentage, so you get 40%

d is 1 1/2 tick marks. It's also asking for percentage. You know 1 tick = 10% and 1/2 tick = 5* so d = 15%

[tex]y\cdot \:2\frac{1}{2} =[/tex] [tex]2\frac{1}{2}=\frac{2\cdot 2+1}{2}=\frac{5}{2}[/tex] [tex]=\frac{5y}{2}[/tex]

a) [tex]2y+\frac{1}{2}=\frac{4y+1}{2}[/tex]

b) [tex]2y+\frac{1}{2}y=\frac{5y}{2}[/tex]

For this question the answer is:

C.

Answer:

a. 88.70% of the variation in the cost is being explained by the resolution.

Step-by-step explanation:

Given :

Summation of (Yi - Ybar)2 = 147172

Summation of (Yhat - Ybar)2 = 130542

Summation of (Y - Yhat)2 = 16630

The Coefficient of determination (R²) :

Sum of Square regression (SSR) / sum of square TOTAL (SST). It gives the percentage of the dependent variable which can be explained by the regression line.

Cost is the dependent variable in this scenario.

SSR = Summation of (Yhat - Ybar)2 = 130542

SST = Summation of (Yi - Ybar)2 = 147172

Hence,

SSR / SST = 130542 / 147172

R² = 130542 / 147172

R² = 0.8870029 = (0.8870029 * 100%) = 88.7%

Answer:

2/3 * 1/3 = 2/9

Step-by-step explanation:

You see the top 2 lines being shaded which is 2/3's of the whole square.

The second shaded part only covers 1/3 of the whole square.

Thus, you multiply both parts to figure out the darkest shaded part!

PEMDAS

PARENTHESIS: [3-10]=7

EXPONENTS: 3^3= 27

MULTIPLICATION:8×7=56

DIVISION:NONE

ADDITION:NONE

SUBTRACTING: 56-27=29

ANSWER: 29

Step-by-step explanation:

you have to have some number for someone to solve it

3x²-5x+2=0

d = b²-4ac

d = (-5)²-4(3)(2)

d = 25-24

d<1

By quadratic formula

x = 5+1/6,5-1/6

x= 1,2/3

Answer:

1) 14

2) m<1=47°

3) m<2=47°

Step-by-step explanation:

1) 75-2x=89-3x

-2x+3x=89-75

x=14

2) m<1=75-2x

75-2(14)

75-28

47

3) m<2=89-3x

89-3(14)

89-42

Step-by-step explanation:

I assume you just want to calculate the cost of making a circle with a diameter of 2.5 feet.

The area of a circle can be calculated using the following formula:   A = pi * r2

The radius of a circle is half of the diameter.  For this problem, the radius will be 2.5 / 2 or 1.25 feet and pi is 3.14

Then the area will be :  A= 3.14 * 1.252

A= 3.14 * 1.5625 = 4.90625 ft2

If each square foot cost $32.50, then the wood will cost $32.50 * 4.90625 = $159.45

Answer:

10.4

Step-by-step explanation:

So let's do the basic, adding. 5 kilometers on Saturday and 4 on part of Sunday. That's 9. So let's save that. Now for the meters. We know that there are 1000 meters in a kilometer. So add up 600 and 800. That gives you 1400 meters total. Now if we divide 1400 by 1000, we get 1.4. So that is how many kilometers he rode on Friday and and the other part of Sunday. SO now we just add everthing up. 9km+1.4km = 10.4, your answer

Answer:

a) 0.1769 = 17.69% probability that both professors get their grants funded.

b) 0.7231 = 72.31% probability that at least one of the professors will be funded.

c) 0.4331 = 43.31% probability that Professor Jane is funded but Professor Joe is not.

d) 0.5989 = 59.89% probability that Professor Jane is funded but Professor Joe is not

Step-by-step explanation:

a. What is the probability that both professors get their grants funded?

Jane has a 0.61 probability of being funded.

Joe has a 0.29 probability of being funded.

So

[tex]p = 0.61*0.29 = 0.1769[/tex]

0.1769 = 17.69% probability that both professors get their grants funded.

b. What is the probability that at least one of the professors will be funded?

None:

Jane has a 1 - 0.61 = 0.39 probability of not being funded.

Joe has a 1 - 0.29 = 0.71 probability of not being funded.

0.39*0.71 = 0.2769

At least one:

1 - 0.2769 = 0.7231

0.7231 = 72.31% probability that at least one of the professors will be funded.

c. What is the probability that Professor Jane is funded but Professor Joe is not?

Jane has a 0.61 probability of being funded.

Joe has a 1 - 0.29 = 0.71 probability of not being funded.

0.61*0.71 = 0.4331

0.4331 = 43.31% probability that Professor Jane is funded but Professor Joe is not.

d. Given at least one of the professors is funded, what is the probability that Professor Jane is funded but Professor Joe is not?

0.4331/0.7231 = 0.5989

0.5989 = 59.89% probability that Professor Jane is funded but Professor Joe is not

= 137°

Answer:

26

Step-by-step explanation:

first, substitute the value for x into the expression. since x = 6, you will be plugging in 6 for x.

4x + 2 ⇒ 4(6) + 2

simplify the expression, starting with 4 · 6.

4(6) + 2 ⇒ 24 + 2

then add 24 + 2.

24 + 2 ⇒ 26

Answer:

The above calculator compounds interest monthly after each deposit is made. Deposits are applied at the beginning of each month. If you want to make deposits at the end of each month, then please subtract the first deposit from the initial savings amount.

Step-by-step explanation:

Your answer is:

V(n) = 30(0.95)^n

Why?

Well here is why!

Rate of decrease = 5%

Period, n = 10 days

Initial stock price = $30

Value of share price as a function of n:

Value, V(n)

Initial price = A

V(n) = Initial price(1 - rate)^n

V(n) = 30(1 - 0.05)^n

V(n) = 30(0.95)^n

Answer:

2.34 cm

Step-by-step explanation:

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

Angle at the centre (θ) = 34°

Radius (r) = 4 cm

Length of chord (C) =?

The length of the chord can be obtained as follow:

C = 2rSine(θ/2)

C = 2 × 4 × Sine(34/2)

C = 8 × Sine 17

C = 8 × 0.2924

C = 2.34 cm

Therefore, the lenght of the chord is 2.34 cm.
