Answer:
29
Step-by-step explanation:
x*2 + y*2
Replace x with the number for x given in the problem.
5*2 + y*2
Do the same with y.
5*2 + 2*2
5 to the second power is just another way to write 5 x 5, and 2 to the second power is just another way to write 2 x 2.
So if we solve 5 x 5 and 2 x 2, we would get...
25 + 4
25 + 4 = 29
The sum of all cars will be = 70 + 30 + 50 + 80 + 20 = 250
So,
<span>the probability that’s the nexts car to drive by will be red = (red cars)/(total cars)
= 50 / 250 = 0.2
</span>
the probability that’s the nexts car to drive by will be <span>blue = (</span><span>blue cars)/(total cars) = 70 / 250 = 0.28
then
</span>
<span>the probability that’s the nexts car to drive by will be red or blue
= 0.2 + 0.28 = 0.48 </span>
Step 1: find the area of the base
A=l*w = 8.25*5.5 = 45.375
Step 2: find the perimeter of the base
P=2l+2w = 2(8.25) + 2(5.5) = 16.5 + 11 = 27.5
Step 3: find the surface area of the prism
SA=2A+Ph = 2(45.375) + 27.5(4.5) = 90.75 + 123.75 = 214.5
Hope this helps
Answer:
46.3
Step-by-step explanation:
Mean is the average of all values. You add all the values on the table and divide them by the amount of values (here there are 10 land animals so you would divide by 10).
If 1/4x - 1/4 = 2 then 2 + 1/4 = 1/4x.
so 3/4 = 1/4x
3/4 is equal to 1/1.33 (reduce by dividing both numerator and denominator by 3)
so 4 x ? = 1.33. 1.33 / 4 = 0.3325
so (if you're solving for x) I believe the answer is x = 0.3325
