Answer:
In a sporting event, the scoring area (shown here) consists of four concentric circles on the ice with radii of 6 inches, 4 feet, 6 feet, and 7 feet. If a team member lands a (43-pound) stone randomly within the scoring area, find the probability that it ends up centered on the given color. (a) red (b) white (c) blue (a) The probability that it ends up centered on red is (Type an integer or a simplified fraction.) (b) The probability that it ends up centered on white is (Type an integer or a simplified fraction.) (c) The probability that it ends up centered on blue is (Type an integer or a simplified fraction.) of the answer boxes
Answer:
y = 2x
Step-by-step explanation:
There is a proportional relation between the number of pairs of socks that Jason buys,x, and the total cost (in dollars), y.
Let us assume that the relation is y = kx ..... (1)
{Where k can be assumed to be the constant of proportionality}
Now, given that Jason can buy 2 pairs of socks for $4.
So, from equation (1), we can write 4 = 2k, ⇒ k = 2
Therefore, the equation (1) becomes y = 2x. (Answer)
If the width is w and the length is l, then 2w+2l=perimeter=34=2*6.5+2l=13+2l. Subtracting 13 from both sides, we get 21=2l and by dividing both sides by 2 we get 10.5
Answer:
the answer is A
Step-by-step explanation:
Answer:
D)
90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
(0.52846 , 0.75166)
Step-by-step explanation:
<u><em>Step:-1</em></u>
Given that the random sample size 'n' = 50
The sample proportion
90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
<u><em>Step(ii):-</em></u>
Level of significance = 0.90
Z₀.₉₀ = 1.645
(0.64 -1.645(0.06788) , (0.64 + 1.645(0.06788)
(0.52846 , 0.75166)
<u><em>Final answer:-</em></u>
90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
(0.52846 , 0.75166)
