Answer:
5.01%
Step-by-step explanation:
In order to calculate a sequence of events you need to multiply the probability of each event happening with one another in decimal form. In this scenario, the probability of James bowling a strike is 55% meaning that the probability of James NOT bowling a strike is 45%. We want to know the probability of James NOT bowling a strike for 3 attempts and then bowling a strike on his fourth attempt. We first turn these probabilities into decimal form by dividing them by 100. And then multiply...
55 / 100 = 0.55
45 / 100 = 0.45
0.45 * 0.45 * 0.45 * 0.55 = 0.05011875
Multiply by 100 to get percentage.
0.05011875 * 100 = 5.01%

Solve for x:
5x - 15 = 2030
Answer:
x=409
Step-by-step explanation:
First add and make the varible on one side of the equation: add 15 to both sides. 5x=2045
Then divide to find x. 2045/5=409

How do you do this question?
Step-by-step explanation:
(a) dP/dt = kP (1 − P/L)
L is the carrying capacity (20 billion = 20,000 million).
Since P₀ is small compared to L, we can approximate the initial rate as:
(dP/dt)₀ ≈ kP₀
Using the maximum birth rate and death rate, the initial growth rate is 40 mil/year − 20 mil/year = 20 mil/year.
20 = k (6,100)
k = 1/305
dP/dt = 1/305 P (1 − (P/20,000))
(b) P(t) = 20,000 / (1 + Ce^(-t/305))
6,100 = 20,000 / (1 + C)
C = 2.279
P(t) = 20,000 / (1 + 2.279e^(-t/305))
P(10) = 20,000 / (1 + 2.279e^(-10/305))
P(10) = 6240 million
P(10) = 6.24 billion
This is less than the actual population of 6.9 billion.
(c) P(100) = 20,000 / (1 + 2.279e^(-100/305))
P(100) = 7570 million = 7.57 billion
P(600) = 20,000 / (1 + 2.279e^(-600/305))
P(600) = 15170 million = 15.17 billion

a
a=-13, b=-13
a=-13, b=13
.
a = 13,b=-13
a = 13,- 13
Answer:
a = 13, b = 13Step-by-step explanation:
In this example predicted value is 87 and actual value is 100
Error is 100 - 87 = 13
Absolute error is same, |100 - 87| = 13
So the correct choice is the last one:
a = 13, b = 13Form a perfect-square trinomial. y = x2 + 2x + − 1−
Answer:
y = x^2+2x+1
Step-by-step explanation:
x^2+2x+1
= (x+1)^2
Answer:
The correct answer is y = x2+ 2x+ 1 − 1− 1

A giant tortoise can travel 0.14 miles in 1 hours .At this rate ,how long would it take to travel 2 miles ?
Answer:
about 14.3 hours
Step-by-step explanation:
The relation between time, speed, and distance can be written any of three ways:
time = distance/speeddistance = speed×timespeed = distance/time__
Here, the question asks for the travel time, so the relevant relation is the first one. Filling in the given values, we have ...
time = (2 mi)/(0.14 mi/h) ≈ 14.29 h
It would take about 14.3 hours to travel 2 miles.

solve the system of linear equations by substitution.
x + 4y = 6
x - y = 1
9514 1404 393
Answer:
(x, y) = (2, 1)
Step-by-step explanation:
Use the second equation to write an expression for x:
x = 1 +y
Substitute that into the first equation:
(1 +y) +4y = 6
5y = 5 . . . . . . . . subtract 1, collect terms
y = 1 . . . . . . . divide by 5
x = 1 +1 = 2 . . . use the expression for x to find x from y
The solution is (x, y) = (2, 1).
