Answer:
P [ K > 3.95] = 0.5633
Step-by-step explanation:
The interpretation of the given question goes thus;
Suppose that K is a random variable
P[-3.95 ≤ K ≤ 3.95] = 0.725
where; P [ + 3.95 < K ] = P [K < - 3.95]
P[K< 3.95] - P [K > - 3.95] =0.725
P [K < 3.95] - [ 1- P[K < 3.95]] = 0.725
P[k < 3.95] - 1 + P [ K < 3.95] = 0.725
3.95 P [ K < 3.95] -1 = 0.725
3.95 P [ K < 3.95] = 1.725
P [ K < 3.95] = 1.725/3.95
P [ K < 3.95] = 0.4367
P [ K > 3.95] = 1 - P[K< 3.95]
P [ K > 3.95] = 1 - 0.4367
P [ K > 3.95] = 0.5633
Answer:
1796.6 m³
Step-by-step explanation:
area of base = 1/2(11 + 16) x 9.5 = 128.33 m²
128.33(14) = 1796.6 m³
Answer:
C
Step-by-step explanation:
because 14 is 7 x 2 the scale factor from the small pyramid to the big pyramid would be 1/2
I used a little trig, the opposite and adjacent were being used so I used tan... I used it to find h and then plugged it in the a=bh
It should be 5, i have uploaded it worked out
