Answer:
The probability that Leon strikes is greater than Carlton strike is 0.40905
Step-by-step explanation:
From the question, we have;
The percentage of Carlton's rolls are strikes, [tex]\hat p_1[/tex] = 70%
The number of games Carlton played, n₁ = 25
The percentage of Leon's rolls that are strikes, [tex]\hat p_2[/tex] = 67%
The number of games Leon played, n₂ = 25
Therefore, we have;
[tex]\hat p=\dfrac{k_1 + k_2}{n_1 + n_2}[/tex]
Where;
k₁ = 0.7 × 25 = 17.5
k₂ = 0.67 × 25 = 16.75
[tex]\therefore \hat p=\dfrac{17.5 + 16.75}{25 + 25} = 0.685[/tex]
The test statistic is given as follows;
[tex]Z=\dfrac{\hat{p}_1-\hat{p}_2}{\sqrt{\hat{p} \cdot (1-\hat{p})\cdot \left (\dfrac{1}{n_{1}}+\dfrac{1}{n_{2}} \right )}}[/tex]
[tex]Z=\dfrac{0.7-0.67}{\sqrt{0.685 \cdot (1-0.685)\cdot \left (\dfrac{1}{25}+\dfrac{1}{25} \right )}} \approx 0.2283[/tex]
From the z-table, we have;
The p-value for Carlton strikes is greater than Leon's strike = 0.59095
∴ The p-value for Leon strikes is greater than Carlton strike = 1 - 0.59095 = 0.40905
The probability that Leon strikes is greater than Carlton strike = 0.40905

if the sum of the interior angles of a polygon is 2340, how many sides does the polygon have?
Answer:
15
Step-by-step explanation:
Where n represent no.of sides
(2n-4)90=2340
180n-360=2340
180n=2340+360
180n=2700
n=15

Step-by-step explanation:
Given in the figure below, find the values of X and Z.
Answer:
x = 6 , z = 79
Step-by-step explanation:
(8x + 53) and (6x + 43) are adjacent angles and sum to 180° , that is
8x + 53 + 6x + 43 = 180 , that is
14x + 96 = 180 ( subtract 96 from both sides )
14x = 84 (divide both sides by 14 )
x = 6
Then
6x + 43 = 6(6) + 43 = 36 + 43 = 79
z and 79 are vertical angles and congruent , then
z = 79
Answer:
x = 6
z = 79
Step-by-step explanation:
We know that angles on a straight line add up to 180.
With this in mind:
(6x+43)° + (8x+53)° = 180hence 14x+96=18014x=84x=6For z:
since x = 6(8x+53)° + z° = 180101 + z = 180z = 79Another approach using the property where opposite angles are equal:
(6x+43) = z79 = zhelp please im so bad at these

Belinda went biking on Saturday and rode for 6\frac{4}{5} miles on Sunday she rode for \frac{2}{3} of the distance she rode on Sunday
Complete question :
Belinda went biking on Saturday and rode for 6 4/5 miles. On Sunday she rode for 2/3 of the distance she rode on Saturday. Write and solve an equation that will help you figure out how far Belinda rode on Sunday
Answer:
4.5333 miles
Step-by-step explanation:
Number of miles biked on Saturday = 6 4/5 miles
Miles on Sunday = 2/3 of miles biked on Saturday
To obtain the distance biked on Sunday :
Fraction of miles biked on Sunday * miles biked on Saturday
Miles biked on Sunday = 2/3 * 6 4/5
Miles biked on Sunday = 2/3 * 34/5
Miles biked on Sunday = (2 * 34) / (3 * 5) = 68/15 = 4.5333 miles

Answer:
675 [tex]ft^2[/tex]
Step-by-step explanation:
The radius is 15, so replace r in the formula with 15
[tex]A=\pi 15^2[/tex]
A = 225 pi
A = 675
(using 3 for pi, since they specified)
Answer: 675
Step-by-step explanation:
A swing hangs from a beam 10 feet high, with the seat hanging 2 feet above the ground. In motion, the swing moves back and forth from -130° to -50° to the horizontal. How far forward and back does the swing move along the ground at the extremes?
Answer:
11.17 ft
Step-by-step explanation:
Since the swing hangs from a beam 10 feet high with the seat hanging 2 feet above the ground, the swing moves in an arc of radius r = 10 ft - 2 ft = 8 ft.
Now, since the swing moves back and forth from -130° to -50° to the horizontal, the length of arc L it moves in is given by
L = Δθ/360 × 2πr where Δθ = change in angle of the swing = θ₂ - θ₁ where θ₁ = -50° and θ₂ = -130°. So, Δθ = θ₂ - θ₁ = -130° -(-50°) = -130° + 50° = -80°.
Substituting r and Δθ into L, we have
L = -80°/360° × 2π(8 ft)
= -8/36 × 16π ft
= -32π/9 ft
= -100.53/9 ft
= -11.17 ft
Ignoring the negative sign, the length of arc L = 11.17 ft. So, the swing moves back and forth 11.17 ft
Joel has a goal to practice his clarinet for 4 ½ hours per week. The list below shows the number of hours Joel has practiced so far this week.
Answer:
3/4 hours
Step-by-step explanation:
Joel has a goal to practice his clarinet for 4 1/2 per week. The list below shows the number of hours Joel has a practiced so far for the week. Monday 1 1/2 hours Wednesday 1 1/4 hours Thursday 1 hour. How many more hours does he need to practice this week to meet his goal?
Total practice hours per week = 4 1/2 hours = 9/2 hours
Hours of practice so far for the week:
Monday = 1 1/2 hours = 3/2 hours
Wednesday = 1 1/4 hours = 5/4 hours
Thursday = 1 hour
Total = Monday + Wednesday + Thursday
= 3/2 + 5/4 + 1
= (6+5+4)/4
= 15/4 hours
How many more hours does he need to practice this week to meet his goal
Hours needed to meet goal = Total practice hours per week - Hours of practice so far for the week
= 9/2 - 15/4
= (18-15)/4
= 3/4 hours
Hours needed to meet goal = 3/4 hours
