Answer:
t = 1/2 ÷ 1/4
t = 2 hours
Step-by-step explanation:
Time spent watching movies = 1/2 of an hour
This accounts for 1/4 of the total time thei spend at mount rushmore.
1/2 = 1/4t
Where t = total time they spent at mount rushmore (hours)
1/2 = 1/4t
Determine the equation to find t
t = 1/2 ÷ 1/4
= 1/2 × 4/1
= 4 / 2
= 2
t = 2 hours
The probability will be 0.32
Step-by-step explanation:
Find the area of the shaded region
Area of a triangle is given by = 1/2 product of base and height of the triangle
Area of a triangle= 1/2*b*h where b is base length and h is height of the triangle
A=1/2*4*4 *2 =16 cm²
Area of the circle = π×r² where r is radius=4 cm and π =3.14
Area of the circle= π × 4×4 =16π =50.24 cm²
The probability that a randomly selected point within the circle falls in the red shaded area will be : P(area of shaded part/area of circle)
p=16/50.24 =0.31847133758
p=0.32 (rounded to the nearest hundredth)

.75 because the more numbers after the decimal point the smaller it gets
I think combine like terms
12x+10x+3x+2x -y+y+5y
X=27 Y=5y
Answer: It is such a small percentage of the population that would be considered to have fever at that level.
So, it is not appropriate stringent standard.
Step-by-step explanation:
Since we have given that
Mean = 98.20°F
Standard deviation = 0.62°F
If Bellevue Hospital in New York City uses 100.6°F as the lowest temperature considered to be a fever.
So, 
So, using the normal distribution, we first find the value of z.

Since z = 3.87
So, p = 0.0001 =0.1%
So,It is such a small percentage of the population that would be considered to have fever at that level.
So, it is not appropriate stringent standard.
