Answer:
Given:
mu = 200 lb, the mean sigma = 25 the standard deviation
For the random variable x = 250 lb, the
z-score is z = (x - mu) / sigma = (250 - 200) / 25 = 2
From standard tables for the normal distribution, obtain
P(x < 250) = 0.977
Answer: 0.977

Answer:
If AB is 16, then AD is 8.
If AB = 12 and CB = 10, then the height of the triangle is 8.
Step-by-step explanation:
AD = [tex]\frac{AB}{2}[/tex], so AD is equal to 8.
Use the Pythagorean Theorem, [tex]\sqrt{10^{2} - 6^{2}}[/tex] equals 8, so the height of the triangle is equal to 8.
a woman is 5 times as old as her daughter in 15 years time to be two times as old as her daughter to find a mother's presentsage
Answer:
25 years.
Step-by-step explanation:
Given that a woman is 5 times as old as her daughter, while in 15 years time it will be two times as old as her daughter, to find a mother's presents age the following calculation must be performed:
5 x 5 = 25
25 + 15 = 40
40/2 = 20
5 + 15 = 20
Thus, the present age of the mother is 25 years, while that of her daughter is 5 years, with which the mother is five times the age of her daughter. In 15 years, the mother will be 40 and her daughter 20, with which she will only be twice her age.

The temperature ws 56 degrees this morning but dropped one degree per hour through
the rest of the day. Write an equation in slope intercept form to represent the situation.
O y = 5.50x + 20
O None of the other answers are correct
O y = 65x
O y = 60x + 300
O y = -x + 56
Answer:
y=-x+56
Step-by-step explanation:
A linear equation is an equation in which each term has at max one degree. The correct option is D, y = -x + 56.
What is a linear equation?A linear equation is an equation in which each term has at max one degree. Linear equations in variables x and y can be written in the form,
y = mx + c
Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.
Given that the temperature was 56 degrees this morning but dropped one degree per hour through the rest of the day. Therefore, an equation in slope intercept form to represent the temperature of the day at any given hour is,
y = 56 - x
y = -x + 56
Hence, the equation in slope intercept form to represent the temperature of the day at any given hour is y = -x + 56.

The amount paid for different weights of oranges at a farmer's market are shown below (A) is the relationship between the price and the weight of the oranges proportional?
Oranges (lb) Price ($)
2--------- $3
3--------- $4.50
5--------- $7.50
Answer:
proportional relationship. Exist
Step-by-step explanation:
To check for propottionality:
2 = 3k
Solve for k = constant of proportionality
2/3 = 3k/3
2/3 = k
Quantity at price = 4.50
Price * k = quantity
4.50 * 2/3 = 3
Quantity at price = 7.50
Price * k = quantity
7.50 * 2/3 = 5
Hence, proportional relationship. Exist

Mary's dog weights 185 pound. Her dog needs to lose between 9 and 15 pounds. Between what two percentages rounded to the nearest whole number, should Mary's dog lose weight with respect to its current weight 185 pounds.
Answer:Mary' s dog should loose weight between 92%-95%
Step-by-step explanation:
Step 1
Mary's dog current weight= 185 pound
weight to loose =Between 9 and 15 pounds
Loosing 9 pounds , the dog"s new weight will be = 185- 9= 176 pounds
also
Loosing 15 pounds , the dog"s new weight will be = 185- 15= 170pounds
Step 2
Percentage of weight loss to current weight when he looses 9 pounds=
= 176/185 x 100
=0.95 x100=95%
Percentage of weight loss to current weight when he looses 15 pounds=
= 170/185 x 100
=0.9189 x100
=91.89= 92%
Therefore Mary' s dog should loose weight between 92%-95%

Answer:

Step-by-step explanation:
Let's fill x and y and we'll see which one is right
a) 0 = -3(-7+7)(-7+4)
<=> 0 = 3 * 0 * -3
<=> 0 = 0 => true
b) 0 = -0.5(-7-7)(-7+4)
<=> 0 = -0.5 * -14 * -3
<=> 0 = -21 => false
c) 0 = (-7-7)(-7-4)
<=> 0 = -154 => false
d) 0 = 2(-7+7)(-7-4)
<=> 0 = 0 => true
so both a and d are right for (-7,0). Now let's for (-4,0)
a) 0 = -3(-4+7)(-4+4)
<=> 0 = 0 => true
d) 0 = 2(-4+7)(-4-4)

When two angles of an isosceles triangle are given in the form of x, then the value of a single angle can have two possible outcomes those are:
X can be [tex]56.66^\circ[/tex]X can be [tex]53.33^\circ[/tex]Given,
Two angles: X and [tex]\rm{X}+10[/tex]
As we know in an Isosceles triangle, the sum of all the angles is equal to[tex]180^\circ[/tex] and any of the two angles can be equal.
There can be two possible outcomes:
Case 1. When the two equal angles are X
[tex]\begin{aligned}\text{X}+\text{X}+(\text{X+10})&=180\\3\text{X}+10&=180\\3\text{X}&=180-10\\\text{X}&=\dfrac{170}{3}\\\text{X}&=56.66^\circ\end{aligned}[/tex]
Case 2: When the two equal angles are [tex]\rm{X}+10[/tex]
[tex]\begin{aligned}\text{X}+(\text{X}+10)+(\text{X}+10)&=180\\3\text{X}+20&=180\\3\text{X}&=180-20\\\text{X}&=\dfrac{160}{3}\\\text{X}&=53.33^\circ\end{aligned}[/tex]
Therefore, the two possible values of X can be [tex]56.66^\circ[/tex] and [tex]53.33^\circ[/tex]

Which of the following is the solution to the equation shown below in terms of the constants a,b,c,d?
Answer:
(2)
Step-by-step explanation:
To find the solution, we must find x in terms of everything else, so I will move everything to the left hand side besides x. Let me know if you don’t understand anything below! :)
Answer:
(2) x = a + (bc - bd)^2.
Step-by-step explanation:
√(x - a)/ b + d = c
√(x - a)/ b = c - d
√(x - a) = bc - bd
Squaring both sides:
x - a = (bc - bd)^2
x = a + (bc - bd)^2
Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?
Answer:
51 meters
Step-by-step explanation:
Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?
We are to find the meters of fencing for the diagonal.
We solve the question using Pythagoras Theorem
= c² = a² + b²
Where
c = Diagonal
a = Width
b =Length
Diagonal² = Width² + Length ²
Hence:
Diagonal ² = 45² + 24²
Diagonal = √45² + 24²
Diagonal = √(2601)
Diagonal = 51 m
Therefore, the meters of fencing for the diagonal that Steve would be needing = 51 meters
