Answer:
y = 5
x = 5
Step-by-step explanation:
find the complete question in the attached image
the angle opposite 5y is also 5y. this is because alternate angles are equal
180 = 155 + 5y
5y = 180 - 155
5y = 25
y = 5
the sum of 5y and 13x is equal to 90
this is because the sum of angle on a straight line is equal to 180 and one of the angle on the straight line is already equal to 90 . so, 90 (180 - 90)
5y + 13x = 90
25 + 13x = 90
13x = 90 - 25
13x = 65
x = 5
The Standard Normal Distribution is a "Bell-shaped" curve as shown in the figure below.
The distribution ha these properties:
(i) The normalized random variable, z, is the horizontal coordinate for the curve.
(ii) The total area under the curve is 1.
(ii) The curve is symmetric about z = 0.
Answer:
As z values decrease, areas to the left of z decrease.
Answer:
The plumber charges £16.50 per hour. this is how to solve it. You minus the callout fee from the total fee which is £167.00- £18.50=£148.50. So you then divide 148.50 by the amount of hours which is 9 hours. so 148.50÷9 = £16.50
Answer:
<E =122
Step-by-step explanation:
The sum of the angles of a triangle is 180
<D + < E + < F = 180
25 + <E + 33 = 180
Combine like terms
58 + <E = 180
<E = 180 -58
<E =122
A: you need to know how many cars you wash an hour. A reasonable amount would be five cars an hour making the equation 24•5=120$
B: you need to know how much the baking molds cost, a reasonable amount would be 7.50, the equation would be 7.50•5=37.5
