Answer:
1.96 ;
1.216
Step-by-step explanation:
Given the data :
x : __0 _ 1 _ 2 _ 3 _4 _5 Total
P(x) .07 .36 .27 .17 .10 .03 1.00
. The mean, also called the expected value is defined as ;
E(X) = Σx*p(x)
E(X) = (0*0.07) + (1*0.36) + (2*0.27) + (3*0.17) + (4*0.10) + (5*0.03) = 1.96
The standard deviation, ; √var(x)
Var(X) = Σx²*p(x) - E(X)²
Var(X) = [(0² * 0.07) + (1² * 0.36) + (2² * 0.27) + (3² * 0.17) + (4² * 0.10) + (5² * 0.03)] - 1.96²
Var(X) = 5.32 - 3.8416
Var(X) =14784

This is a scale drawing of a house where 1 centimeter represents 0.6 meters. What is the height of the house at its highest point? Round to one decimal point, if necessary.
Answer:
Height of the house = 3 meter (Approx.)
Step-by-step explanation:
Given:
Scale model;
1 centimeter = 0.6 meter
According to graph
Height of cube = 5 cube = 5 centimeter
Find:
Height of the house
Computation:
Height of the house = height of the house in scale model x Scale model
Height of the house = 5 x 0.6
Height of the house = 3

A textbook store sold a combined total of 331 physics and sociology textbooks in a week. The number of sociology textbooks sold was 45 less than the number
of physics textbooks sold. How many textbooks of each type were sold?
Answer: Number of sociology books sold = 143 books
Number of physics books sold = 143 + 45 = 188 books
Step-by-step explanation:
Let us take the number of sociology books sold = x
Number of physics books sold = x+45
So now we can form an equation
x+x+45 = 331
2x+45 = 331
2x = 331-45
2x = 286
x = 286 ÷ 2
x = 143

Answer:
Step-by-step explanation:
The supplement of the exterior angle is 180 - 75 = 105
In a cyclic quadrilateral (a four sides figure where all the vertices touch the circumference of a circle), the opposite angles are supplementary. Therefore <a = 180 - 105 = 75
But I think you already knew that.
what’s the answer for the first question? pls help i don’t have much time…
Answer and Step-by-step explanation:
1.
Since we known how much money Jane and Mark have in total, we can subtract the amount Jane has to find the amount Mark has.
750 - 175 = $575
Mark has $575.
2.
We know how many cards Jamal sold, so if we add it to the amount he still has left, we can find the original amount of cards Jamal had.
17 + 83 = 100
Jamal had 100 cards.
#teamtrees #PAW (Plant And Water)
Answer:
Mark will have $575.
Step-by-step explanation:
Take the total amount ($750) and subtract Jane's contribution ($175) to get Mark's contribution($575).
$750-$175=$575
Solve for y, given that b=22(Round your answer to 1 decimal place, if necessary.)
Answer:
37.7
Step-by-step explanation:
First, we have to divde 22/7 to find the scale factor. I chose 22 and 7 because those two sides are ocngruent. We get 3.14. We then have to multiply 12 by 3.14 beacuse that is the side that is congruent with the side y. When you multiply you should get 37.68. Since we have to round we get 37.7.

Math problem. If answered correct will give brainliest
Please answer :)
Answer:
Step-by-step explanation:
45n = (9 x 25) + 4 + (2x4)
45n = 225 + 4 + 8
45n/45 = 237/45
n = 5.26666...7
exactly 5.26666...7 buses would be needed.
realistically 6 buses are needed, as you cannot have part of a bus operating like a normal one
the exact answer can be classified as a rational number as it can represent a fraction.
In the last 6 days, Laura has
jogged 39 miles. At what rate did
Laura jog each day?
A: 234 miles per day
B: 33 miles per day
C: 6.5 miles per day
D: 0.15 miles per day
Answer:
6.5 miles per day

Take the number of miles and divide by the number of days
39 miles/ 6 days
6.5 miles per day
Answer: 6.5 miles per day is correct
Step-by-step explanation:
You would just need to divide 39 by 6 to find the total miles per day. Therefore C: 6.5 is correct!

In the figure below j ll h find the values of x and y
Answer:
26
Step-by-step explanation:
Given: Lines J and H are parallel lines. O intersects both lines equally.
Since two angles equal 180, that will be what (4y + 12) and 64 will be equal to.
(4y + 12) + 64 = 180
76 + 4y = 180
-76 -76
-------------------
4y = 104
y = 26
x and y is both 26 because they are vertical angles.
Hope this helped.
