What is the area of the region bounded by the lines x= 1 and y= 0 and the curve y=xe^x^2?
Answer:
A = 0.859
Step-by-step explanation:
We want to find the area of the region bounded by the lines x = 1 and y = 0 and the curve y = xe^(x²).
At y = 0, let's find x;
0 = xe^(x²)
Solving this leads to no solution because x is infinity. Thus we can say lower bound is x = 0.
So our upper band is x = 1
Thus,lets find the area;
A = ∫xe(x²) dx between 1 and 0
A = (e^(x²))/2 between 1 and 0
A = ((e¹)/2) - (e^(0))/2)
A = 1.359 - 0.5
A = 0.859
The ratio of red to blue marbles in a bag is 3:2. If there are 20 total marbles in the bag, how many blue marbles are in the bag?
Answer:
8
Step-by-step explanation:
Let's say there are 3*x red marbles in the bag. As the ratio of red to blue is 3:2, that means that there are 2*x blue marbles in the bag. The total marbles are then
3*x+2*x= 20
= 5x
Divide both sides by 5 to get
x=4
2*x is the amount of blue marbles, and 2*x = 8

Answer:
-24+6=
Step-by-step explanation:
select the correct rule, then solve the equation
Complete Question
Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. minimum=7, maximum = 83, 6 classes
What is the class width? (whole number)
We have that the Class Width is given as
7-19
20-32
33-45
46-58
59-71
72-84
Generally
[tex]Class\ width =\frac{83-7}{6}[/tex]
Class width =12.67
Class width =13
Hence
Lower class limit is
7,7+13=20...33,46,59,72
Upper class limit is
7+13-1=19,32,45,58,71,84

If two parents, one with brown eyes (a dominant trait) and the other with blue eyes (the recessive trait) produce one twin boy with blue eyes, what is the probability that a fraternal twin will transmit the blue eye allele to his or her offspring
Answer:
50 percent
Step-by-step explanation:
It is given that one of the parent with a dominant trait have brown eyes and the other parent with a recessive trait has blue eyes. They produce a twin boy with eyes that is blue in color. So the probability of the fraternal twin to transmit his allele of blue eye to his or her offspring is 50 percent.
And also the probability of the offspring to pass the allele on to his or her offspring is 50 %.
The product rule is used : 0.5 x 0.5 = 0.25 or 25%.

How many groups of 3/4 are in each of the following questions?
11/4
Enter answer as a fraction.
Answer:
12 1/3
Step-by-step exp
First, you need to add up 11/4 and
6 1/2
11/ 4 + 6 1/2 = 11/4 + 13/2 = 37 / 4
To find how many 3/4 we have in 37/4, we simply dividw 37/4 by 3/4
37/4 ÷ 3/4
= 37/4 × 4/3 (4 will cancel out 4)
= 37/3

The value of the permutation expression P(6, 1) will be 6.
What are permutation and combination?A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.
Evaluate the expression P(6, 1).
We know that the formula for the permutation is given as,
ⁿPₓ = n! / (n - x)!
From the above, the value of n is 6 and the value of x is 1. Then we have
⁶P₁ = 6! / (6 - 1)!
⁶P₁ = 6! / 5!
⁶P₁ = 6 x 5! / 5!
⁶P₁ = 6
The value of the permutation expression P(6, 1) will be 6.

Explanation:
Sides ED and FD are the same length due to the red tickmarks.
The angles opposite these side lengths, angle E and angle F, are congruent as well. So angle F is also x.
For any triangle, the three angles always add to 180
F+E+D = 180
x+x+74 = 180
2x+74 = 180
2x+74-74 = 180-74 .... subtract 74 from both sides
2x = 106
2x/2 = 106/2 ... divide both sides by 2
x = 53
As a check,
F+E+D = x+x+74 = 53+53+74 = 180
which verifies the answer.

Alaina went to the pet store to buy fish for her new 14-gallon fish tank. Each large fish costs $8 and requires 2 gallons
of water. Each small fish costs $3 and requires 0.5 gallon of water. She has $70 to spend on fish at the pet store. Circle
the combination of large and small fish can Alaina purchase for her fish tank?
Answer:
Small fish= 7
Big fish= 21/4 (so she'll get 5 big fish)
Step-by-step explanation:
With the problem, there are two equations, one for the cost, and one for the amount of water. For the first equation, Alaina can spend 70 dollars and the fish cost 8 and 3 dollars so the equation is 70=8b+4s (s for small and b for big). Then for the second equation there are 14 available gallons and the fish require 2 and .5 gallons so 14=2b+0.5s. Then you just solve the system of equations.
