Dave drives to work each morning at about the same time. His commute time is normally distributed with a mean of 47 minutes and a standard deviation of 5 minutes. What percentage of time is his commute less than 52 minutes?
Answer:
0.15866
Step-by-step explanation:
First, we calculate z-score
Mathematically;
z-score = value-mean/SD
here, mean = 47 , SD = 5 and value = 52
z-score = (52-47)/5 = 5/5 = 1
The probability we want to calculate is;
P(z<1) and we can access this from the standard score table
P(Z<1) =0.15866
Find the equation of the line with slope 6 passing through (3,20) y=mx+b
Answer:
y = 6x + 2
Step-by-step explanation:
Step 1: Write known variables
y = 6x + b
Step 2: Solve for b
20 = 6(3) + b
20 = 18 + b
b = 2
Step 3: Rewrite

The distance between point (-3,6) and another point is 10. What are the possible
coordinates of the other point?
Answer:
The distance between point A(-3,6) and another point is 10.
=> That point belongs to the circle with center A and radius 10.
=> The coordinate (x, y) of that point satisfies the equation of circle:
(x - -3)^2 + (y - 6)^2 = 10^2
or
(x + 3)^2 + (y - 6)^2 = 100

given the function f(x)= 2|x+6|-4, for what values of x is f(x)=6?
Answer:
x = -1 or x = -11
Step-by-step explanation:
f(x)= 2|x+6|-4
2|x+6|-4 = 6
2|x+6| = 6+4
2|x+6|=10
|x+6| = 10/2
|x+6| = 5
x+6 = ±5
x = ±5 - 6
x = -1 or x = -11

The transformation from function f(x) =3x to the function f(x)=3x-2
Answer:
Translation down 2 units
Step-by-step explanation:
If a number is added or subtracted like that at the end of a function, it will either lift or put down a function however many units the number says. In this case, the number says 2, so the transformation would be a "Translation down 2 units".

Bablu has three sticks of lengths 3, 4 and 5 cm. Ramesh has three sticks of lengths 3, 5 and 9 cm. How many triangles can Bablu and Ramesh make with their sticks?
Answer: 1 triangle
Step-by-step explanation:
From the question, we are told that Bablu has three sticks of lengths 3, 4 and 5 cm and Ramesh has three sticks of lengths 3, 5 and 9 cm. To make a triangle, the addition of the square I the two smallest lengths must be equal to the square of the length of the largest stick. This will be:
Bablu has three sticks of lengths 3, 4 and 5 cm. This will be
3² + 4² = 5²
9 + 16 = 25
Since this is equal, Bablu sticks can make a triangle.
Ramesh has three sticks of lengths 3, 5 and 9 cm. This will be:
3² + 5² = 9²
9 + 25 = 34
Since the answer is 34 and not 9² which is 81, it means that Ramesh can not make a triangle. Therefore, only 1 triangle can be made.
A sandwich shop is ordering apples and grapes to make chicken salad. Apples cost $2.19 per pound and grapes cost $2.60 per pound. If they ordered a total of 20 pounds of apples and grapes and paid $35.80, how many pounds of grapes did they order?
We got $19.51 but we think it is wrong.
Answer:
Less than 13 pounds of grapes,
as 14 pounds of grape exceeds $35.80,
If you order as low as zero pounds of grapes, then the price of apple pounds would be $35.80/20 =$1.79 per pound
Step-by-step explanation:
Let
Quantity of Apple and grapes=20
Cost of apple=$2.19
Cost of grape=$2.60
Total cost of apple and grape=$35.80
a+g=20
a=20-g
PaQa+PgQg=35.80
2.19(20-g)+2.60g=35.80
43.8-2.19g+2.60g=35.80
0.41g=35.80-43.8
0.41g=-8
g=-8/0.41
g= -19.51
PaQa+PgQg=35.80
2.19a+2.60(-19.51)=35.80
2.19a-50.726=35.80
2.19a=35.80+50.726
2.19a=86.526
a=86.526/2.19
=39.51
PaA+PgG=35.80
Pa(20-G)+2.60G=35.80
35.80/2.60 = 13.77 pounds of grapes, but no money will be left to buy apples, unless Pa=0
G<13.77

Alicia can choose 2 of her 5 best friends to go with her to the amusement park. Her best friends are Connie, Dale, Eric, Finley, and Georgette. How many different pairs of 2 friends can she choose from the 5 ?
Answer:
2
Step-by-step explanation:
5/2= 2.5 ((or 2 1/2) (or 250%) any you prefer) But you can't get half a person to come in the amusement park so we round it down (2.5 → 2)
So the answer is 2
The different pairs of 2 friends can she choose from 5 is 20.
What is Permutation?A permutation is an ordered arrangement of outcomes and an ordered combination.
We have already seen the basic permutations formula in the previous section. Here are different permutations formulas that are used in different scenarios.
For example, there are 5 chairs and 3 persons are to be seated. We have 5 ways to seat the first person; 4 ways to seat the next person and 3 ways to seat the third person. Thus, to find the number of ways for arranging 3 persons in 5 chairs, we multiply the options available to us. We do it in 5 × 4 × 3 ways. i.e., it can be done in 60 ways. Observe that 5 × 4 × 3 can be written as
(5!) / (2!) (or) (5!) / (5 - 3)!.
Generalizing this, we get n options to fill the first chair, n-1 options to fill the second and n-2 options to fill the third chair. Thus, the total number of permutations (arrangements) of r people in n chairs can be expressed as: nPr = n! / (n - r)!.
Given:
n= 5, r=2
Using Permutation,
[tex]^{n}P_r[/tex] = n!/ ( n-r)!
= 5!/ 3!
=5*4*3!/ 3!
=5*4
=20
Hence, in 20 different ways pairs of 2 friends can she choose from the 5.

Answer:
x = 116°
y = 90°
Step-by-step explanation:
∠F = 90°, so arc EDS = 180°.
Therefore, arc EFS = 360° − 180° = 180°. Which means ∠D = 90°.
Angles of a quadrilateral add up to 360°, so:
x + 90° + 90° + 64° = 360°
x = 116°
Answer:
The value of x is 116° and y = 90°
Step-by-step explanation:
Given that opposite supplementary angles in a cyclic quadrilateral is 180° :
[tex]x + 64 = 180 \\ x = 180 - 64 \\ x = 116[/tex]
[tex]y + 90 = 180 \\ y = 180 - 90 \\ y = 90[/tex]
