Volume of a sphere formula is: V=4
/3 πr^3
You know v=17000 and pi=3.14
17 000 = 4/3 x 3.14 x r^3
(divide 17 000 by 4/3 x 3.14 ) --> r^3 = 4060.51 (2dp)
(cube root is to get just r) r = 15.95 inches (2dp)
There 15 inches to the nearest inch.
Hope this is correct! :D
Answer:
A coordinate grid that shows a point located halfway between 3 and 4 units to the right and 1 unit down from the origin
Step-by-step explanation:
In a coordinate grid, the y axis is plotted on the vertical axis and the x axis is plotted on the horizontal axis. A is plotted on a coordinate grid at (
) i.e (
). Above the origin is the positive y axis, below the origin is the negative y axis, right of the origin is the positive x axis and left of the origin is the negative x axis.
To plot A on the coordinate axis we need to locate 
on the x axis and -1 on the y axis. is halfway between 3 and 4, since the x coordinate is positive it is located to the right between 3 and 4 and since the y coordinate is negative it is located 1 unit down from the origin.
Answer:
Her grocery bill is $4.62
Step-by-step explanation:
The first step is to multiply 6 and .43 to get how much it was for all of the apples.
Then the next step is to do the same thing with the oranges.
Then the last step is to add the two together.
Answer:
it is a two tailed test
The p - value for z=1.92 is 0.9726
Using a significance level of α=0.10, We fail to reject H0. The calculated z value lies out side the Zα value.
Step-by-step explanation:
For p≠0.767
Taking null hypothesis as p≠0.767 and alternate hypothesis as p =0.767
H0 :p≠0.767 Ha :p≠0.767 it is a two tailed test
The p - value for z=1.92 is 0.9726 from the table.
Using a significance level of α=0.10
z value for 0.10 for two tailed test is ± 1.645
Z >zα
1.92> ± 1.645
Using a significance level of α=0.10, We fail to reject H0. The calculated z value lies out side the Zα value.
Step-by-step explanation:
To find out how much she spent:
30 - 27.15 = 2.85
Change it to cents:
2.85 x 100 = 285 cents
Calculate how many yards of ribbon she bought:
285 / 19 = 15
Therefore, she bought 15 yard of ribbon.
