Answer:
flying disc
Step-by-step explanation:
The formula of the circumference of circles is: diameter ×
I will find the circumference of each object to see if it matches the circumferences on the table.
Half dollar coin: 3
= 10 (rounded to nearest integer) CORRECT!
Flying disc: 23
= 72 (rounded to nearest integer) WRONG!
Jar lid: 8
= 25 (rounded to nearest integer) CORRECT!
Flower pot: 15
= 48 (rounded to nearest integer) CORRECT!
Based on the table, it was recorded that the circumference of the flying disc is 28, but we have calculated based on the diameter that it should be 72, so the measurement is inaccurate.
(Y+22) + 3 = Y + 22 + 3 = Y + 25
Answer:
The claim is false.
Step-by-step explanation:
Given the data :
13 24 21 37 15 25 18 22 40 32
The sample mean and standard deviation can ben calculated for the given sample.
Using calculator :
Sample mean, xbar = 24.7
Sample standard deviation, s = 9.04
Sample size, n = 10
The hypothesis :
H0 : μ = 17
H1 : μ ≠ 17
The test statistic :
(xbar - μ) ÷ (s/√(n))
(24.7 - 17) ÷ (9.04/√(10))
7.7 / 2.8586990
Test statistic = 2.694
We can obtain the Pvalue, at α = 0.05 ; df = n-1 = 9
Pvalue = 0.0246
Since Pvalue < α ; we reject the null ; Hence, there is significant evidence to conclude that an adult American does not spend average of 17 hours in leisure
Answer:
kkkkkkkllllll
Step-by-step explanation:
llllllllllllllllllllllllll
78 - 45 = 33
Since it’s half a number you do
33 x 2 = 66
So the answer is 66
