The weights of newborn elephants are normally distributed with a mean of 225 pounds and a standard deviation of 45 pounds. Find the probability that a newborn elephant weighs more than 210 pounds.
Answer:
0.63043
Step-by-step explanation:
Given that :
Mean = 225
Standard deviation = 45
P(x > 210) : (x - mean) / standard deviation
P(x > 210) = (210 - 225) / 45
P(x > 210) = - 0.333
P(Z > - 0.333) = 0.63043 (Z probability calculator)

Answer:
3/5 = 0.6 = 60%
16/25 = 0.64 = 64%
11/20 = 0.55 = 55%
4/25 = 0.16 = 16%
17/100 = 0.17 = 17%
7/20 = 0.35 = 35%
A new truck that sells for $29,000 depreciates 12% each year.
Write a function that models the value of the truck.
Answer and Step-by-step explanation:
f(x) = [tex]29,000(0.88)^{x}[/tex]
Where x is time in years and f(x) is the amount of money the truck is worth each year.
We get 0.88 by subtracting 0.12 (aka 12%) from 1.00.

Required
Which other ratio equals [tex]\frac{HL}{JL} =\frac{IL}{KL}[/tex]
[tex]\triangle[/tex]HLI ~ [tex]\triangle[/tex]JLK implies that:
HL, IL and HI corresponds to JL, KL and JK respectively.
So, the possible ratios are:
HL : IL : HI = JL : KL : JK
Convert to fractions
[tex]\frac{HL}{JL} = \frac{IL}{KL} = \frac{HI}{JK}[/tex]
So, from the list of options
[tex]\frac{H I}{J K}[/tex] is equivalent to [tex]\frac{HL}{JL} =\frac{IL}{KL}[/tex]

Write an equation of the line passing through the point (5,8) that is parallel to the line 7x + 5y = 3.
Answer:
y-8=-7/5(x-5)
Step-by-step explanation:
find the slope by rewriting the line's equation.
5y=3-7x
5y=-7x+3
y=-7/5x +3/5
since its parallel, the slope will be the same (-7/5)
use the formula y-y1=m(x-x1) for the point (5,8)
y-8=-7/5(x-5)
rearrange in the form y=mx+b if you wish.

Answer:
x ≈ 14.7
Step-by-step explanation:
Assuming the triangle is right then use Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 15² = 21²
x² + 225 = 441 ( subtract 225 from both sides )
x² = 216 ( take the square root of both sides )
x = [tex]\sqrt{216}[/tex] ≈ 14.7 ( to the nearest tenth )

g(x) =
A. g(x) = (x + 4)2 - 1
O B. g(x) = (x-4)2-1
ASAP plzzzz help
Answer:
The answer is g(x)=(x-2)^2+1
Step-by-step explanation:
The equation of the blue graph is y = (x - 4)² + 1.
Option D is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The graphs of y = x² and y = (x - 4)² + 1 are both parabolas.
The graph of y = x² is a simple upward-facing parabola that passes through the origin.
As x increases or decreases, the value of y increases but at an increasingly slower rate until it reaches a minimum at x = 0, where it turns back upwards and continues to increase at an increasingly faster rate.
The graph of y = (x - 4)² + 1 is also a parabola, but it is shifted 4 units to the right and 1 unit up compared to y = x².
Thus,
The equation of the blue graph is y = (x - 4)² + 1.

Answer:
11
Step-by-step explanation:
x= -b/2a
x= -8/2(-2)
x=-4/-2
x=2
f(2) = -2(2) +8(2)+ 3
f(2) = -8 +16 + 3
f(2) = 11
Maximum value is 11
Answer:
11
Step-by-step explanation:
it has a vertex at (2,11)
.
f(2) = 11
how to find the vertex;
function equation is f(x) = ax^2 + bx + c
we can find x by :-b/2a, -8/-4 = 2

Y=6-x In this case, what would be the slope and y-intercept? I'm having a hard time trying to get it to the y=mx+b format.
Answer:
Slope = [tex]\frac{-1}{1}[/tex] or -1
y = 6
Step-by-step explanation:
The equation given (y = 6 - x) is the same as saying
y = -1x + 6
Since we have a negative x variable and a positive 6 and would also be graphed the same. The only difference is that the second equation I just mentioned resembles the y = mx + b expression more. In this case the slope would be
Slope = [tex]\frac{-1}{1}[/tex] or -1
While the y-intercept would be
y = 6 - x
y = 6 - 0
y = 6

Answer:
a; d = 20n
Step-by-step explanation:
you can use the process of elimination and an example problem to help!
so if mason mowed 2 lawns, he'd make $40, right? now you could try each equation to see which one equals $40
a. d = 20(2) ⇒ d = 40
b. n = 20d ⇒ 2 = 20d ⇒ d = 0.1
c. d = 20 ÷ n ⇒ d = 10
d. n = 20 + d ⇒ 2 = 20 + d ⇒ d = -18
therefore, your answer would be A!
