Find the area of the triangle

Cerrena [4.2K]

Answer:

Part 1) $P=204\ yd$

Part 2) $A=1,325\ yd^2$

Step-by-step explanation:

Part 1)

we know that

The perimeter of triangle is equal to the sum of its length sides

$P=54+97+53=204\ yd$

Part 2)

we know that

The area of triangle is given by the formula

$A=\frac{1}{2}(b)(h)$

we have

$b=53\ yd\\h=50\ yd$

substitute

$A=\frac{1}{2}(53)(50)=1,325\ yd^2$

Scores on a biology final exam are normally distributed with a mean of 220 and a standard deviation of 16. Determine the percent

IrinaK [193]

Answer:

86.64%

Step-by-step explanation:

Mean (μ) = 220

σ= 16

n= 4

mean score(X) = 220 -12

= 208

Using central limit theorem which says that for a sample of size (n), the standard error is

standard deviation /√n

= 16/√4

= 16/2

= 8

Standard error = 8

Using Z score

Z = (μ - x) / standard error

Z= (220 -208)/8

Z= 12/8

Z= 1.5

From the table, Z = 1.5 = 0.4332

Since the normal distribution curve is symmetrical, we have

0.4332*2

= 0.8664

Percentage = 0.8664*100

= 86.64%
