Answer:
There is a 84% probability that the seed will germinate. (Poor plants)
Step-by-step explanation:
250 = 100%
210 = x
250x = 21000
x = 84
Formula for volume of cylinder is area of base time height
area of base equal pir^2 =3,14*(2,5)^2 = 3,14 *6,25 = 19,625 inches squared
V=area time height
170 = 19,625 *h
h = 170/19,625 = 8,662 inches
AVERAGE between 90 and 100%
means not including 90 and 100% but not including 90 or 100%
average=(sum of values in set)/(how many values in the set)
so
4 exams, so there are 4 values
average=(sum)/4
the sum is the known+unknwon
sum=76+99+86+x
so
90<span><</span>average and average <span><</span>100
or
90<span><</span>average<span><</span>100
lets say average=a
a=sum/number
a=(76+99+86+x)/4
90<(76+99+86+x)/4<100
90<(76+99+86+x)/4 and (76+99+86+x)/4<100
solve each for x and find intersection
90<span><</span>(76+99+86+x)/4
times 4 both sides
360<span><</span>261+x
minus 261 both sides
99<span><</span>x
(76+99+86+x)/4<u><</u>100
times 4 both sides
261+x<u><</u>400
minus 261 both sides
x<u><</u>139
so
99<u><</u>x<u><</u>139
since max score is 100
99<u><</u>x<u><</u>100
interval notaion is
[99,100]
answer is 2nd one
Answer:
plz mark brainliest..
Step-by-step explanation:
AC is the hypotenuse = 10
AB is side opposite to <C
<C = 30°, <B = 90°
by 30°-60°-90° theorem
side opposite to 30° is equal to half of hypotenuse
therefore,
AB = 1/2 × AC
AB = 1/2 × 10
AB = 5
therefore number 5 is answer
hope it will help you
The mean sustained wind velocity has the equation:
v = 6.3 √(1013 - p)
If we are given with the mean sustained wind velocity of 64 m/s, then we can solve for the air pressure using the equation:
64 = 6.3 √(1013 - p)
64/6.3 = √(1013 - p)
10.1587² = 1013 - p
p = 910 millibars
hope this helps!!!!!!!!!!!!
