Answer:

Pete

Step-by-step explanation:

Given that:

Mandy's Estimate :

Number of spins , n = 20

Pete's Estimate:

Number of spins, n = 200

A good probability estimate is one which has narrow margin of error with a high degree of confidence. These two variables are affected by sample size.

A high sample size give a narrower margin of error and increases the confidence level probability

Based on the sample size used by each of Pete and Mandy, we can conclude that, Pete's probability estimate would be better due to its significantly higher sample size.

Step-by-step explanation:

39=6+9y

                                          39-6=9y

                                           33=9y

                                          33/9=y

                                           33/9=11/3                                                  

Answer:

The x = 102

Step-by-step explanation:

The whole angle is 180 so you have to do 180-78 to get the other angle .

Answer:

x = 102

Step-by-step explanation:

x + 78 = 180 {linear Pair}

      x = 180 - 78

     x = 102

Answer:

y = (2/5)x + 3

Step-by-step explanation:

Note that the y-intercept is (0, 3) and that the line passes right through the point (5, 5).  First we find the slope of this line:  m = rise/run.

As we move from (0, 3) to (5, 5), we see that x increases by 5 (the run) and y increases by 2 (the rise).  Thus, the slope of this line is m = 2/5.

Now we know that m = 2/5, x = 5, y = 5 and b (the y-intercept) is 3.  Then our equation is y = mx + b, or y = (2/5)x + 3

Answer:

The equation is [tex]y = \frac{2}{5} x+3[/tex]

Step-by-step explanation:

The line of best fit has an x-intercept of 3, so the constant in the equation would be 3. Since one of the points on the line is (5, 5), the change in y over the change in x (the slope) is going to be [tex]\frac{5-3}{5-0}[/tex] or [tex]\frac{2}{5}[/tex]. So the line's equation is [tex]y = \frac{2}{5} x+3[/tex].

Answer:

f = 4n

f = n+27

Fred is 36 years old and Nathan is 9 years old.

n = 9

Step-by-step explanation:

Answer:

Step-by-step explanation:

Ooh I love these type of problems

Okay, here we go :

f = Fred and n = Nathan

  f = 4n

  f = n + 27

Above are the two equations (the words translated into algebra)

Now you can solve using substitution (any method works, but substitution is easiest for this problem)

4n = n + 27

3n = 27

n = 9

Since n = 9 substitute n into either equation

f = 4 * 9

f = 36

Fred is 36 and Nathan is 9

Answer:

Prime factorization of 28 and 35 is (2 × 2 × 7) and (5 × 7) respectively. As visible, 28 and 35 have only one common prime factor i.e. 7.

Answer:

40 degrees

Step-by-step explanation:

the angles of a triangle add up to 180 degrees,

180 = x + 85 + 55

180 = x + 140

40 = x

Answer:

3x+2y-8=0

Step-by-step explanation:

The equation 3x+2y=8 in general form is 3x + 2y - 8 = 0 respectively.

A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We are given that  the equation 3x+2y=8.

The equation of straight line is written as y = mx + c

3x+2y=8.

2y = 8 - 3x

y = 8/2 - 3/2x

y = 4 - 3x/2

Hence, the general form is 3x + 2y - 8 = 0.

Step-by-step explanation:

Answer:

0N

Step-by-step explanation:

Force = mass * acceleration

Given

Mass = 5kg

velocity = 19m/s

IF the velocity of the body is constant, then the acceleration will be zero.

Force = 5 * 0

Force = 0N

Hence the net  force on the rock is 0N

Answer:

Total distance covered = 436 yards

Step-by-step explanation:

Walking path BE joins the midpoints B and E of the sides AC and AD.

By midsegment theorem,

"Line joining midpoints of two sides of a triangle is parallel and measure half of the third side"

m(BE) = [tex]\frac{1}{2}[m(CD)][/tex]

CD = 2(BE)

CD = 2(74) = 128 yd

From starting point D,

DE = 107 yd

EB = 74 yd

BC = [tex]\frac{254}{2}[/tex]

     = 127 yd

CD = 128 yd

Total walking distance = DE + EB + BC + CD

                                      = 107 + 74 + 127 + 128

                                      = 436 yd

Total distance covered = 436 yards

Answer:

456

Step-by-step explanation:

107

74

254/2 =127

74x2=148

107+74+127+148=456

Answer:

Radius = 6 ft

Diameter = 12 ft

Circumference = 37.7 ft

Step-by-step explanation:

The radius of the circle is the measurement from the center of the circle to the edge. The diagram gives us the radius, 6 ft.

Radius = 6 ft

The diameter of the circle is the measurement from the edge of the circle through the center, extending back to the edge. The diameter is equal to double the radius.

6*2=12

Diameter = 12 ft

The circumference of the circle is the distance around its edge or the perimeter of the circle. We use the below equation to solve for it:

[tex]C=\pi d[/tex] where [tex]d[/tex] is the diameter

Plug the diameter (12) into the equation

[tex]C=\pi (12)\\C=37.7[/tex]

(This answer is approximate)

Circumference = 37.7 ft
