Answer:
1. n = 1/2
2. m = 5/3 or 1 2/3
3. a = 1/4
4. x = 27/8
5. x = 13/6
Step-by-step explanation:
I'm just going to explain step 5 as that is what you specifically needed help with.
First, simplify the second term of the equation:
-6(2.5x-3)
= -15x + 18
(this was done by multiplying -6*2.5x which is 15x and -6(-3) which is 18)
Now, add this simplified second term back to the first term:
3x + 8 - 15x + 18
(the parentheses are unnecessary now because it is all just addition and subtraction, so the order doesn't matter)
Simplify:
-12x + 26 = 0
= -12x = -26
= x = -26/-12
= x = 13/6
Hi!
Lets walk through this together.
Lets start with the top.
4-8 is -4.
what that line is- its pretty much telling you to divide.
-4 divided by 3 is -1.3~ (infinant 3's)
-1.3~ Is your answer. Hope this helps!
You can multiply each fraction on both top and bottom so that they have 24 as the denominator. The equation becomes
subtract 16/24 to both sides and you get
now subtract 20/24 from both sides and
<u />
multiply 24 on both sides
-26=21m
and divide by 21 on both sides
m=-26/21 or -1.24

Answer:
P(G) = 0.55
the probability of getting an offspring pea that is green. Is 0.55.
Is the result reasonably close to the value of three fourths that was expected?
No
Expected P(G)= three fourths = 3/4 = 0.75
Estimated P(G) = 0.55
Estimated P(G) is not reasonably close to 0.75
Step-by-step explanation:
Given;
Number of green peas offspring
G = 450
Number of yellow peas offspring
Y = 371
Total number of peas offspring
T = 450+371 = 821
the probability of getting an offspring pea that is green is;
P(G) = Number of green peas offspring/Total number of peas offspring
P(G) = G/T
Substituting the values;
P(G) = 450/821
P(G) = 0.548112058465
P(G) = 0.55
the probability of getting an offspring pea that is green. Is 0.55.
Is the result reasonably close to the value of three fourths that was expected?
No
Expected P(G)= three fourths = 3/4 = 0.75
Estimated P(G) = 0.55
Estimated P(G) is not reasonably close to 0.75
