Answer:
y=5.79x
Step-by-step explanation:
What you'll first do it divide both sides by y
So, y/y =5.79x/y
so the answer for question 1 is going to be 5.79xy.
If this is from the textbook, use slader. it might help you better than me.
Now do the same thing for the second one.

A statistics class has a population of 140 students of which 55% are female. A random sample of 40 students was selected. What is the probability that 24 or more from this sample will be female?
Answers
Answer:
The probability that 24 or more from this sample will be female is 0.2643.
Step-by-step explanation:
Define X as the number of female students.
The random variable X follows a Binomial distribution with parameters n = 40 and p = 0.55.
But the sample selected is too large and the probability of success is close to 0.50.
So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:
1. np ≥ 10
2. n(1 - p) ≥ 10
Check the conditions as follows:
[tex]np=40\times 0.55=22>10\\\\n(1-p)=40\times (1-0.55)18>10[/tex]
Thus, a Normal approximation to binomial can be applied.
So, X follows normal distribution with mean and standard deviation:
[tex]\mu=np=40\times 0.55=22\\\\\sigma=\sqrt{np(1-p)}=\sqrt{40\times 0.55\times (1-0.55)}=3.15[/tex]
Compute the probability that 24 or more from this sample will be female as follows:
[tex]P(X\geq 24)=P(\frac{X-\mu}{\sigma}>\frac{24-22}{3.15})\\\\=P(Z>0.63)\\\\=1-P(Z<0.63)\\\\=1-0.7357\\\\=0.2643[/tex]
Thus, the probability that 24 or more from this sample will be female is 0.2643.

Answer:
[tex]M_{2}=\frac{F_{g}r^{2}}{GM_{1}}[/tex]
Step-by-step explanation:
To find [tex]M_{2}[/tex], you can manipulate the formula.
[tex]F_{g}=\frac{GM_{1}M_{2}}{r^{2}}[/tex] (given)
[tex]F_{g}r^{2}=GM_{1}M_{2}[/tex] (times r² on both sides)
[tex]M_{2} = \frac{F_{g}r^{2}}{GM_{1}}[/tex] (divide both sides by [tex]GM_{1}[/tex])
∴ [tex]M_{2}=\frac{F_{g}r^{2}}{GM_{1}}[/tex] in terms of [tex]F_{g}, G, M_{1}[/tex] and [tex]r[/tex]
Find the length of the missing side. The triangle is not drawn to scale.
Answers
Answer:
c = 10
Step-by-step explanation:
To find the hypotenuse of the triangle you would do the value of leg^2 + leg^2 to find the hypotenuse. Or you can look at it like a^2 + b^2 = c^2. But in order to get the value you would have to find the scare root of c^2.
----------------------
In this case though we are doing 6^2 + 8^2 which equals 100. After calculating that we know c^2 power equals 100. So know you have to find the actual value of c by itself to get your hypotenuse. So we would find the square root of 100 which is 10. Hope this helps!!
---------------------
Important words
Hypotenuse - In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.
Cathetus (legs of triangle) - Either of the sides that are adjacent to the right angle.

Answer:
the awnswer is -10
Step-by-step explanation:
Remember a negative times a negative is the only time the answer will be positive. When a negative is multiplied by a positive it will always be negative.
ex:
-2 x 5
since this is a negative and a positive the answer will be negative. knowing that just multiply 2x5=10 then add the negative -10.

Use two formulas for volume to find the volume of the figure. Express the answer in terms of x and then round to nearest whole number.
Answers
Answer:
Volume of the figure = 341.3π + 1,280π = 1,621.33π
Volume of the figure to the nearest whole number = 1,621π m³
Step-by-step explanation:
The figure shown is composed of a hemisphere and a cylinder.
The volume of the figure = volume of hemisphere + volume of cylinder
Volume of the hemisphere = ⅔πr³
Radius (r) of hemisphere = 16/2 = 8 m
Volume of hemisphere = ⅔*π*8³ = ⅔*π*512 = 341.33π m³
Volume of Cylinder = πr²h
radius (r) = 16/2 = 8 m
height (h) = 20 m
Volume of cylinder = π*8²*20 = 1,280π m³
Volume of the figure = 341.3π + 1,280π = 1,621.33π
Volume of the figure to the nearest whole number = 1,621π m³
