Your answer would be 0.14 to the nearest hundredth.
The question P(Walk to school | Senior) is asking for the probability that a student walks to school given that they're a senior. Therefore we have to count how many total senior students there are, which is 35.
To form the probability, we then need to see how many of these 35 students walk to school, which we're given as 5. Thus, the probability is 5/35 which simplifies to 1/7.
1/7 as a decimal is 0.1429, which, when rounded to the nearest hundredth, gives us 0.14.
I hope this helps! Let me know if you have any questions :)

A board game uses a fair six-sided die and a spinner with five-equal sized sections colored dark blue, green, light blue, red, and yellow. Players roll the die then spin the spinner. Match each probability to its correct value. The probability of getting a
Answer:
[tex]\frac{1}{30}[/tex]
Step-by-step explanation:
The computation of the probability is shown below:
P(die and spinner) is
= Probability of the die × probability of the spinner.
where,
Probability of the die is
= [tex]\frac{1}{6}[/tex]
And for the spinner, the probability is
= [tex]\frac{1}{5}[/tex]
Therefore the probability of both die and inner is
= [tex]\frac{1}{6} \times \frac{1}{5}[/tex]
= [tex]\frac{1}{30}[/tex]
We simply multiplied the probabilities of both die and spinner

Step-by-step explanation:
If f(x)=8-10x and g(x)=5x+4, what is he value of (fg)(-2)
Answer:
168
Step-by-step explanation:
We would like to multiply these two expressions together and then substitute -2 in for x to solve.
f(x) * g(x) = (8 - 10x) * (5x + 4)
We will use FOIL (first, outer, inner last):
(8 - 10x) * (5x + 4) = 8 * 5x + 8 * 4 + (-10x) * 5x + (-10x) * 4
Combining terms, we get:
f(x) * g(x) = 32 - 50x²
Plug -2 in for x:
32 - 50 * (-2)² = 32 - 50 * 4 = 32 - 200 = -168
The answer is thus 168.

Sam was building a suspension bridge for the playground at an elementary school and needed some chain link and rope.He bought a total of 80 feet of materials. The chain link cost $2.00 per foot, and the rope cost $1.50 per foot. He spent a total of $135. How much of eacb did he buy?
Answer:
30 feet of chain link and 50 feet of rope
Step-by-step explanation:
Let's call the amount of chain link as x and the amount of rope as y. We can write:
x + y = 80 -- Equation 1
2x + 1.5y = 135 -- Equation 2
2x + 2y = 160 -- Equation 3 (Multiply Equation 1 by 2)
0.5y = 25 (Subtract Equation 2 from Equation 3)
y = 50 (Divide by 2)
x + 50 = 80 (Substitute y = 50 into Equation 1)
x = 30 (Subtract 50)

-35/8
Step-by-step explanation:
-7/4 = (2/5)*t (-7*5)/(4*2) = t t= -35/8What is the length of arc FE?
Answer:
4.42
Step-by-step explanation:
Angles A and C are identical because the two circles are similar.
The arc length formula is s = rФ, where r is the radius and Ф is the central angle.
If we know s and r, then the central angle Ф is s/r, or, in this case,
Ф = 8.84/5.
Now let's find the length of the arc EF: s = rФ becomes:
s = (2.5)(8.84/5) = 4.42
Can someone help me with this question please?
Answer:
If the ratio of edge lengths is 3:5, I'm going to assume that the perimeters are going with the same ratio.
Therefore, the ratio would be 345:575.
Hope this is right and helps :)
6.1 1 a) and b) Let x be a string of length n, and let y be a string of length n − k, for 1 ≤ k < n. We wish to line up the symbols in x with the symbols in y by adding k blanks to y. a) Suppose that we decide to add the k blanks in one continuous block. How many ways are there to do this? b) Suppose that we add two separate blocks of blanks, one of size i and one of size k − i, for 1 ≤ i < k. How many ways are there to do this?
Answer:
A) N-k+1 possible ways
B) 8 ways ( different outcomes )
Step-by-step explanation:
A) length of X = n
length of Y = n - k
number of ways to add k blanks in one continuous block
that would be n - k +1 and this because since we already have n-k blanks in y already
B ) how many ways to add two separate blocks of blanks
one size is ; i
one size ; k - i
The number of ways will be 8 since the block of blanks are separated into two blocks
In the triangles, HG = MP and GK = PN. Triangles H G K and M P N are shown. Side H K has a length of 15 millimeters. Side M N has a length of 11 millimeters. Sides H G and M P are congruent. Sides G K and P N are congruent. Which statement about the sides and angles is true?
Answer:
m∠G > m∠P
Step-by-step explanation:
Given that:
HG = MP and GK = PN., Side H K has a length of 15 millimeters. Side M N has a length of 11 millimeters.
The triangle law for unequal sides states that if two sides are unequal. the angle opposite the longer side is greater than the angle opposite the shorter side. Since side HK has a length of 15 millimeters and Side MN has a length of 11 millimeters, the angle opposite side HK (which is m∠G) is greater than the angle opposite side MN (which is m∠P). That is m∠G > m∠P.

A.
Step-by-step explanation:
Line segment ON is perpendicular to line segment ML.
What is the length of chord ML?
A) 20 units
B) 24 units
C) 26 units
D) 30 units
Answer:
24 units
Step-by-step explanation:
OM = ON, so
OP= 13-8
That means OP is 5.
Using the Pythagorean Theorom to find MP:
5^2+b^2=13^2
25+b^2=169
b^2=169-25
b^2=144
B=12
This means MP =12. ML is twice as long as MP. 12x2=24
The answer is B. 24 units

Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 36 feet^3 cubed. Syrus isn't sure if the tent will be tall enough for him to sit up inside. What is the height of the tent?
The dimensions of the tent is in the attachment.
Answer: Height = 4.5 ft
Step-by-step explanation: The image in the attachment shows a rectangular piramid, which means that the base of the piramid is a rectangle with sides 4 ft and 6 ft for width and length, respectively.
The volume of a rectangular piramid is given by the formula:
V = [tex]\frac{1}{3}[/tex].w.l.h
36 = [tex]\frac{1}{3}[/tex].4.6.h
h = [tex]\frac{36.3}{4.6}[/tex]
h = 4.5
The height of the given tent is 4.5 feet.

Answer:
WXYZ can not be a rectangle because consecutive sides are not perpendicular to each other.
Step-by-step explanation:
The given vertices are W(-4,3), X(1,5), Y(3,1) and Z(-2,-1).
Plot these points on coordinate plane and draw the quadrilateral as shown below.
[tex]Slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Using this formula, we get
[tex]m_{WX}=\dfrac{5-3}{1-(-4)}=\dfrac{2}{5}[/tex]
[tex]m_{XY}=\dfrac{1-5}{3-1}=\dfrac{-4}{2}=-2[/tex]
Now,
[tex]m_{WX}\times =\dfrac{2}{5}\times (-2)=-\dfrac{4}{5}\neq -1[/tex]
Here, WX and XY are two consecutive sides of quadrilateral but the product of their slopes is not equal to -1. It means they are not perpendicular to each other.
Since, all interior angles of a rectangle are right angles, therefore, WXYZ can not be a rectangle.

Answer:
x is 46.67
y is 28.4°
Step-by-step explanation:
To solve for x we use sine
sin ∅ = opposite / hypotenuse
AC is the opposite
x is the hypotenuse
so we have
sin 59° = 40 / x
x sin 59 = 40
Divide both sides by sin 59
x = 40/sin 59
x = 46.67
To solve for y we also use sine
sin y = 30/ 63
y = sin^-1(30/63)
y = 28.4°
Hope this helps you
