Answer: 18
Step-by-step explanation:
The probability of this event is 424=1/4. Then the probability of 5th toss is head is 1/2. Hence, in the end the answer is 14⋅12=18.
Answer:
24.76 mine
Step-by-step explanation:
The first thing is to calculate the area of the region, which we can calculate since we have the density and the population. The area would be the quotient between population and density:
260000/135 = 1925.93
The area would be 1925.93 square mine
We know that the area is given by:
A = pi * r ^ 2
we solve to r
r ^ 2 = A / pi
r ^ 2 = 1925.92 / 3.14
r ^ 2 = 613.3
r = 24.76
the radius is equal to 24.76 mine
Answer:
Step-by-step explanation:
20%. 53.17 times .8 is 42.54 meaning there's a 20% decrease
Multiply 2 and 3 also multiply 4 and 5 and then divide the products together like so 2x3 divided by 4x5 so 6 divided by 20
Answer:
y = 0x + 4 or y = 4.
Step-by-step explanation:
The slope is zero, and in other words, m = 0.
The slope intercept form is y = mx + b.
Replace m with 0.
y = 0m + b.
The y intercept is the y point on the line. Since this slope is a straight horizontal line, the y point given is the y intercept. b is the y intercept.
y = 0m + 4
Since any number times 0 is 0 you can right it as
y = 4.
