Answer and Step-by-step explanation:
This is as far as the expression can be simplified.
The undistributed version of the expression is:
9 -5(b - m)
#teamtrees #PAW (Plant And Water)
simplify the expression by using the distributive property 2(3x-5)
Step-by-step explanation:
multiply the outer term to the inner term
so, 6x-10.
Hello.
Let's use the Distributive Property to simplify the given expression.
Remember, the Distributive property states that
a(b+c)=ab+ac
Now, let's simplify our expression:
2(3x-5)
6x-10
This is the simplified answer; we can't simplify it anymore.
I hope it helps.
Have an outstanding day. :)

Triangle DIG is reflected across the l-axis.
O (x, y) --> (-x, y)
O (x, y) --> (-X, -y)
(x, y) --> (y,x)
O (x,y) --> (x,-))
helpp its for a timed assignment
there is not such thing as an I axis, but I will show you what happens for both x and y axis so you can fill out the assignment with the correct information.
IF you meant flipping over the x axis, then the dot will go from top to bottom, bottom to up, the x position won't change only its height(y position)
This meant that for reflecting across the x axis, (x,y)->(x,-y)
For y axis its the opposite, just flipping to the side.
This meant that for reflecting across the y axis, (x,y)->(-x,y)

Step-by-step explanation:
Based on concerns raised by his preliminary research, the biologist decides to collect and examine 150 frogs.
a) Assuming the frequency of the trait is still 1 in 8, determine the mean and standard deviation of the number of frogs with the trait he should expect to find in his sample.
b) Verify that he can use a Normal model to approximate the distribution of the number of frogs with the trait.
c) He found the trait in 22 of his frogs. Do you think this proves that the trait has become more common?
Explain.
Answer:
Answered and explained below
Step-by-step explanation:
A) We are told that frequency of the trait is still 1 in 8. Thus, population proportion; p = 1/8 = 0.125
Sample size; n = 150
Formula for mean is;
μ = np
μ = 150 × 0.125
μ = 18.75
Formula for standard deviation is;
σ = √(np(1 - p))
σ = √(150 × 0.125(1 - 0.125))
σ = √16.40625
σ = 4.05
B) usually, when np ≥ 10 , we make use of normal distribution.
I'm this case, it is 18.75 which is greater than 10.
Thus,we can use a normal model to approximate the distribution.
C) we are told that he found the trait in 22 of the frogs.
Thus;
Proportion is now; 22/150 = 0.1467
This is a higher probability that the initial one of 0.125 and we can say that the trait has become more common.
If the volume of a hemisphere is 92160 pie cubic cm then find
its radius.
Answer:
radius = 51.70 cm
Step-by-step explanation:
Volume = (2/3) π r³
Volume = 92160 π
Radius = ?
Using the above formula
V = (2/3) π r³
r³ = v/((2/3) π)
r³ = ((92160 π) x 3) / (2 x π)
r³ = 276480/2 because (π/π) = 1
r³ = 138240
Taking cube root on both sides
r = 51.70 cm
pls hurry if you can. A What is the volume of this cube?

State if the triangles in each pair are similar. If so, state how you know they are similar and complete the similarity statement.
QRS ~ ____
a. similar, SAS, QLK
b.similar, AA, LQK
c. not similar
d. similar, SSS, LQK
Answer:
. similar, AAA QLK
Step-by-step explanation:
<K=<L base angle of isosceles triangle
<R=<S base angle of isosceles triangle
<KQL=<RQS vertically opposite angle
so
<K=<L=<R=<S
so
∆QRS~QLK by AAA axiom
for similar all the corresponding angle should be equalWhat is the slope of the line that contains these points?
х

10 2
14
26
Answer:
6
Step-by-step explanation:
The slope (m) can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
Any pair of points will do. We can use the first two.
m = (2 -(-10))/(17 -15) = 12/2
m = 6
The slope of the line is 6.
Can someone please help
Answer:
12x+3x=15+6
15x=21
divide both sides by 15
x=7/5
Answer:
hey well use transposition method in this
so 12x-15=6-3x
so.12x+3x-15=6 (we transposed-3 to other side so it became +3)
15x-15=6
15x=6+15
15x=21
X=21/15
X= 1.4
