She can buy 4 boxes of cereal
3+2.25+2.25+2.25= 9.75+2.25=12
Answer:
625 unit²
Step-by-step explanation:
Surface area of a rectangular pyramid :
Area of base * 4(area of triangular side)
Area of base = length * width
Area of base = 15 * 15 = 225
Height of triangular side = 15
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 *15 * 15 = 112.5 unit²
Surface area = 225 + 4(112.5)
Surface Area = 225 + 450
Surface Area = 625 unit²
Answer:
The correct answer is 0.5.
Step-by-step explanation:
The probability of a spinner landing on the shaded part follows binomial distribution.
Equation to be used is P(r) =
×
×
, where n is the number of times the spinner is spun and r is the number of times the spinner falls on the shaded region.
The probability of the spinner landing on the shaded part is p =
. The probability of it landing on the unshaded part is q =
.
The spinner is spun n = 3 times.
We need to find the probability of it landing on the shaded part r = 2.
∴ Putting the values in the equation gives,
P(r) =
×
×
= 3 ×
×
= 0.5
