Area of square base:
13 x 13 = 169
Area of triangular sides:
B x H/2
13 x 16/2 = 104
104 x 4 = because there are 4 triangular sides of the figure = 416
416 + 169 = 585in^2
590in^2
Circumference is 40 in and area is 150 in²
Step-by-step explanation:
- Step 1: Find the circumference of the circle when radius = 7 in
Circumference = 2πr = 2 × 22/7 × 7 = 44 in ≈ 40 in
- Step 2: Find the area of the circle.
Area = πr² = 22/7 × 7² = 154 in² ≈ 150 in²
C) because the 7 and x right next to each other represents multiplication. so it's:
7x=91
7X(Allison's money)=91
Answer: 0.8137
Step-by-step explanation:
As per given , we have
Sample size : n= 47
Let 
be the sample mean o.
Then, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds will be :
[∵ 
]
[By using p-value calculator]
Hence, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds= 0.8137
Answer:
one
Step-by-step explanation:
for general form : ax²+bx+c=0
delta = b²-4ac
so for this example delta is 8²-4×2×8 =0
we know if delta = 0 , we have just one real number solution
so the answer is 1
