I'm taking a class in geometry and I don't know how to work out these kind of questions ​

Answer:

The correct answer is B. 0.75.

Step-by-step explanation:

In order to solve this problem, we just need to add the probabilities of all the age groups that include 35-64.

35-44 Age Group Probability: 0.14

45-54 Age Group Probability: 0.29

55-64 Age Group Probability: 0.32

0.32 + 0.29 + 0.14 = 0.75

Therefore, the correct answer is B. 0.75.

Hope this helps! :D

Answer:

30 degrees

Step-by-step explanation:

Keep this in mind, ALL triangles must equal 180 degrees.

This is an acute triangle, hence one of the angles is 90 degrees. To find the other two angles, we must solve for x. Since we know the sum of all angles in this triangle must equal 180 degrees, we know for setting up our equation, all the angles should equal 180.

[tex]90 + (x+37) + (x+67) = 180\\[/tex]

Now solve for x by isolating x

[tex]2x + 194 = 180\\2x=-14\\x=-7[/tex]

Our x is -7, now that we know that the numerical value of x is -7, replace x with -7 for angle A.

-7 + 37 = 30

<A is 30 degrees.

Check your work

Plug in -7 where you see x.

[tex]90 + (x+37) + (x+67) = 180\\90 + (-7+37) + (-7+67) = 180\\90 + 30 + 60 = 180\\180 = 180[/tex]

Turns out this was a 30-60-90 triangle. ✅

Answer:

y= 3x + 5

Step-by-step explanation:

If it is parallel it has the same slop so we know mx = 3x

then solve for b

-1 = 3(2) + b

-1 = 6 + b

5 = b

Answer:

7 6/7 or 7.8571429

Step-by-step explanation:

The simplest form of the given expression (3/7) x (2/3) is 2/7.

The expression is given as:

(3/7) x (2/3)

The numerator will be 3 x 2 = 6, and the denominator will be 7 x 3 = 21.

So, the simplified form of (3/7) x (2/3) is 6/21.

However, we can further simplify this fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 3.

Dividing 6 and 21 by 3 gives us 2 and 7 respectively.

Therefore, the simplest form of (3/7) x (2/3) is 2/7.

Answer:

60%

Step-by-step explanation:

first you make a fraction. 30 ore girls and thats your numerator. the denominator is 50. make it a whole 100 on the denominator. what you do to the bottom fraction you do to the top. we multiple by 2, so 30 is now 60. 60/100. reduce it to its lowest 3/5. divide 3 by 5. its .6. which is 60%

Answer:

The null hypothesis would be

H0: μ1=μ2=μ3     (all the means of the three sites are equal)

Step-by-step explanation:

Site I          Site II          Site III

28                47               46

54                22               27

44                65               40

16                 56               22

21                 17                58

36

The null hypothesis would be

H0: μ1=μ2=μ3     (all the means of the three sites are equal)    against the claim

Ha:  μ1≠μ2≠μ3  (all the means of the three sites are not equal)

Which if H0 is true, has an F -distribution with v1=k-1 and v2= n-k degrees of freedom.

ANOVA (one way of analysis of variance ) can be applied to test this hypothesis.

Answer:

164.73 cm²

Step-by-step explanation:

Area of the shaded area = area of semi-circle - area of the triangle

Area of the semi-circle:

Area = ½(πr²)

r = ½ of 34 = 17 cm

π = 3.14

Area = ½(3.14 × 17²)

Area = 453.73 cm²

Area of the triangle:

Area = ½*b*h

b = 34 cm

h = 17 cm

Area = ½ × 34 × 17

Area = 289 cm²

Area of the shaded area = 453.73 - 289 = 164.73 cm²

Answer:

(c) 1.6

Step-by-step explanation:

Calculation for what the margin of error will be approximately

First step is to calculate Total hours spent

Total hours spent = (197 * 23.5 hours)

Total hours spent =4,625 hours

Second step is to find the square root of the sample size

Sample size=√197

Sample size=14.04

Third step is to divide the Standard deviation of 8.7 hours by square root of sample size of 14.04

= 8.7 hours /14.04

= 0.6196

Fourth step is to use the Z table to find Z value at 99% confidence

Z value at 99% confidence = 2.58

Last step is to calculate the Margin of error

Margin of error = 0.6196 * 2.58

Margin of error = 1.59857

Margin of error= 1.6 (Approximately)

Therefore what the margin of error will be approximately is 1.6

Answer:

Part A: 14x + 2

Part B: CJ's order is $30, and Cameron's order is $58.

Step-by-step explanation:

Part A: The total cost of the order would be $14 multiplied by the amount of canteens, plus the shipping price of $2. This is what my expression represents.

Part B:

CJ's Order:

14(2) + 2 =

28 + 2

$30

Cameron's Order:

14(4) + 2 =

56 + 2 =

$58

Answer:

11 boxes

Step-by-step explanation:

14 didived by 4 is 10.25 so if you round you should get 11 .

Answer:

4, If you round.

Step-by-step explanation:

If you divide the 14 by 4, you get 3.5 and you can't really break the box in half.

So, you would have to use 5.

The bounded region in question is a triangle in the second quadrant. The line y = 2x + 6 has intercepts (0, 6) and (-3, 0), so revolving the triangle about the x-axis forms a cone with height 3 and whose circular base has radius 6. Its volume would then π/3 • 6² • 3 = 36π ≈ 113.1 units³.

But you're probably supposed to use calculus. Using the disk method, the integral for the volume is

[tex]\displaystyle V=\pi\int_{-3}^0 (2x+6)^2\,\mathrm dx[/tex]

[tex]\displaystyle V=\pi\int_{-3}^0(4x^2+24x+36)\,\mathrm dx[/tex]

[tex]V=\pi\left(\dfrac43x^3+12x^2+36x\right)\bigg|_{-3}^0=\boxed{36\pi}[/tex]

as expected.

Answer:

x = 2

AB = 14

DC = 14

Step-by-step explanation:

If opposite sides are congruent, then:

AB = DC

AB = 3x + 8

DC = x + 12

Thus:

3x + 8 = x + 12

Collect like terms

3x - x = -8 + 12

2x = 4

Divide both sides by 2

x = 2

AB = 3x + 8

Plug in the value of x

AB = 3(2) + 8 = 14

DC = x + 12

Plug in the value of x

DC = 2 + 12 = 14
