Answer:
0.5962
Step-by-step explanation:
Given that :
p = 61% = 0.61
q = 1 - p = 1 - 0.61 = 0.39
n = 154 ; x = 93
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x>=93) = p(x=93)+p(x=94)+...+p(x=n)
P(x>= 93) = 0.59619
P(x>= 93) = 0.5962

y- 4/5=1
what does y equal to?
Answer:
y=1.8
Step-by-step explanation:
first change the fraction into a decimal.
4/5 =0.8
plus the 0.8 to both sides
y=1.8
Answer:
[tex]y - \frac{4}{5} + \frac{4}{5} = 1 + \frac{4}{5} \\ y = \frac{5 + 4}{5 } \\ y = \frac{9}{5} [/tex]

What is the degree of the polynomial f (x) = 23 – 25 – 10
6
3
10
5
Answer:
x=−12
Step-by-step explanation:
Let's solve your equation step-by-step.
x=23−25−10
Step 1: Simplify both sides of the equation.
x=23−25−10
x=23+−25+−10
x=(23+−25+−10)(Combine Like Terms)
x=−12

Answer:
A
Step-by-step explanation:
I think you are in geometry I learned this a little back...
It's hard to explain but basically one side is just (n) another is (n(square root sign))and another is (2n.)
So the answer Is a because in this case (n) is 4

Factor the expression
15x+35y
Answer:
5(3x+7y)
Step-by-step explanation:
In able to factor, it would require to find the least common number between x and y. In this scenario, it would be 5.
Answer:
You're going to get 5(3x + 7y)
Step-by-step explanation:
Simplifying
15x + 35y
Factor out the Greatest Common Factor (GCF), '5'.
5(3x + 7y)
Final result:
5(3x + 7y)

Notice that there are similar triangles here:
[tex]\triangle ABD \sim \triangle FED[/tex][tex]\triangle ACD \sim \triangle AEF[/tex]Set up proportions to find the values of x, y, and z.
[tex]\displaystyle \text{Equation I: }\frac{FD}{AD} = \frac{FE}{AB}[/tex][tex]\displaystyle \text{Equation II: } \frac{A F}{AD}=\frac{EF}{CD}[/tex]Let's make this problem simpler by incorporating only 2 variables instead of 3. Let's say that the total distance between the two poles is distance d. Instead of z, let's call it d - y.
Substitute known values or variables into the proportions.
[tex]\displaystyle \text{Equation I: } \frac{d-y}{d} = \frac{x}{6}[/tex][tex]\displaystyle \text{Equation II: }\frac{y}{d}= \frac{x}{12}[/tex]Cross-multiply and simplify Equation I.
[tex]6(d-y)=dx[/tex] [tex]6d-6y=dx[/tex]Cross-multiply and simplify Equation II.
[tex]12y=dx[/tex]We now have two equations that are equal to dx, so we can set them equal to each other.
[tex]6d-6y=12y[/tex]Add 6y to both sides of the equation.
[tex]6d=18y[/tex]Divide both sides of the equation by 6.
[tex]d=3y[/tex]We can substitute this value of d back into either Equation I or II. I am going to substitute d into Equation II.
[tex]\displaystyle \frac{y}{3y} = \frac{x}{12}[/tex]Cross-multiply and simplify the equation.
[tex]12y=3xy[/tex]Divide y from both sides of the equation.
[tex]12=3x[/tex]Divide both sides of the equation by 3.
[tex]4=x[/tex]The guylines from the top of one pole to the bottom of the other cross at the height of 4 ft off the ground.

A store pays $22 for a surfboard. The store marks up the price by 37%. What is the amount of the mark-up?
Answer:
$8.14
Step-by-step explanation:
Given data
Cost of surfboard= $22
Mark up = 37%
Required
The amount of the markup
let us find 37% of $22
=37/100*22
= 0.37*22
= $8.14
Hence the amount of the markup is $8.14

A man wants to enclose a rectangular garden adjacent to a river. The length of the rectangle is two times the width. How many linear feet of the fence must he buy if he does not need fencing along the river and the perimeter of the rectangle is 240 feet?
Answer:
200, 160
Step-by-step explanation:
if perimeter is 240 it means sides are 40 by 80.
if he does not need to place fencing on one side, they remove one 80 or 40,
40+80+80=160 or 40+40+80=200
Boom Awser
Answer:
200 160
Step-by-step explanation:
if the perimeter is 240, the length is 80 and width is 40.
40+80+80=200
80+40+40=160
