The probability that Terry buys a sandwich is 0.4.
The probability that Terry gets the bus is 0.9.
Assuming the events are independent, what is the probability that Terry buys a sandwich and gets the bus?
Answer:
The probability that Terry buys a sandwich and gets the bus is 0.36
Step-by-step explanation:
When two events are called independent, it means that the happening of one event doesn't affect the happening of other event.
Let A be the event that Terry buys a sandwich
Let B be the event that Terry gets the bus
Then
[tex]P(A) = 0.4\\P(B) = 0.9[/tex]
When two events are independent, their probabilities are multiplied i.e.
[tex]P(A\ and\ B) = P(A) * P(B)\\= 0.4 * 0.9\\= 0.36[/tex]
Hence,
The probability that Terry buys a sandwich and gets the bus is 0.36

The pair of points lies on the same line with the given slope. Find x.
(5,8). (x,14); slope = 2
Find x.
(Type an integer or a simplified fraction.)
Answer:
required Value of x is x=8
Step-by-step explanation:
We are given two points: (5,8) and (x,14) and slope =2 . We need to find value of x.
The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given slope =2 , x₁=5, y₁=8, x₂=x, y₂=14
So, we actually need to find value of x₂. Putting values in formula and find value of x
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\2=\frac{14-8}{x-5}\\Solving:\\2(x-5)=6\\2x-10=6\\2x=6+10\\2x=16\\x=\frac{16}{2}\\x=8[/tex]
So, required value of x=8

Step-by-step explanation:
Just add all the percentages together and divide it by the number of scores, which in this case is 5.
Answer:
83.2%
Step-by-step explanation: we know, mean = sum of data/ number of data
= 78+82+89+83+84

Find the value of x that makes m ∥ n .
Answer:
60
Step-by-step explanation:
(2x+15)=135 They're corresponding angles so they equal/congruent
-15 -15 Subtract 15 on both sides since you're looking for x
2x = 120 Bring down the remains and subtract 135 from 15
2 2 Add 2 on both sides
x= 60 Divide.

If you remember nothing else from this section remember:
arc length = radius * angle
s = r * q
where the angle, q, is measured in radians.
There are other formulas, but that one is pretty important.
48. A circular arc of length 3 feet subtends a central angle of 25.
Find the radius of the circle.
Start with s = r*q , s = 3 feet, q = 25 = 25*(p/180) = (5/36)p radians
3 = r * (5/36)p Å 3*(36/5) = r*p Å 21.6 = p*r Å r = 21.6/p feet
52. Memphis, Tennessee and New Orleans Louisiana lie approximately on
the same meridian. Memphis has latitude 35 N and New Orleans 30 N.
Find the distance between the cities, given the radius of the earth is
3960 miles.
Again start with s = r*q,
with r = 3960 miles and q = 35 – 30 = 5 = 5*(p/180) = (1/36)p.
and we need to find s = arc length = distance between the cities.
s = 3960*(1/36)p = 110p miles.
60. A sector of a circle of radius 24 miles has an area of 288 square miles.
Find the central angle of the sector.
For this you need a new formula.
The area of a sector of circle = A = ½*r
2
*q ,
where q is the central angle of the sector measured in radians
and r of course is the radius of the circle.
For this problem r = 24 miles, A = 288 sq. miles and we need to find q.
288 = (½)*24
2
*q Å 288 = 288*q Å 1 radian = q (or about 57.3)
62. Three circles with radii 1, 2 and 3 feet are externally tangent to one
another. Find the area of the sector of the circle of radius 1 that is
cut off by the line segments joining the center of that circle to the
centers of the other two circles.
So you start out with:
Notice you know the length of ALL the sides of the triangle, because you know
the radius of each circle. From this you might discern that: 5
2
= 3
2
+ 4
2
. Thus you
have the (length of the hypotenuse)
2
= (length of side A)
2
+ (length of side B)
2
.
And from that you may conclude the triangle is a right triangle, or rather the angle
we are interested in is 90. Thus we use the area formula given in the text:
The area of a sector of circle = A = ½*r
2
*q ,
For this problem r = 1 foot, q = 90 = p/2, and we need to find A
A = ½ * 1
2
* p/2 = p/4 square feet.
Step-by-step explanation:
The linear speed of a point on the equator in miles per hour is 1037 mph. Therefore, option D is the correct answer.
Given that, the radius of the earth is approximately 3960 miles.
What is the linear speed?Linear speed is the measure of the concrete distance travelled by a moving object. The speed with which an object moves in the linear path is termed linear speed. In easy words, it is the distance covered for a linear path in the given time. Linear Speed Formula is articulated as s=rθ/t.
Any point in the equator would complete a 360° or 2π, revolution in 24 hours. Therefore, the linear speed would be s=rθ/t.
where r is the radius of the Earth and θ is the angular distance (in rad) after time t
Hence, the linear speed would be
s= (3960×2π)/24
= (3960×2×3.14)/24
= 24868.8/24
= 1036.7
≈1037 mph
The linear speed of a point on the equator in miles per hour is 1037 mph. Therefore, option D is the correct answer.

In a ten pin bowling the highest possible score in a single game is 300. At one point in the season, John had an average score of 177. In his next game he obtained a score of 199 which caused his average to increase to 178. After one more game John would like his average to be 183. is it possible for him to accomplish this. If so what score does he need to make his next game if not explain why not.
Answer:
John need to get 293 in his next game to bring his average up to 183.
Step-by-step explanation:
John starts with N games played and averaging 177 points per game.
In game N+1, John scored 199 points.
[tex]\frac{177N + 199}{N+1}=178\\177N+199=178N+178\\N=21\\[/tex]
So, John has now played (N+1) = 22 games.
We need to know what score John needs in game 23 to bring his average to 183.
[tex]\frac{177*21 + 199+Y}{23}=183\\3916+Y=4209\\Y=293\\[/tex]

Find the distance between the two points G(-1,-5) and H(3,-8)
Answer:
5.099
Step by step explanations:
Input Data :
Point 1(xA,yA)(xA,yA) = (4, 3)
Point 2(xB,yB)(xB,yB) = (3, -2)
Objective :
Find the distance between two given points on a line?
Formula :
Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2
Solution :
Distance between two points = √(3−4)2+(−2−3)2(3-4)2+(-2-3)2
= √(−1)2+(−5)2(-1)2+(-5)2
= √1+251+25
= √2626 = 5.099
Distance between points (4, 3) and (3, -2) is 5.099
