Answer:
Step-by-step explanation:
The answer is 22 percent.
Brand X cost: $4.50
Brand Y cost: $3.50
Christopher spends total: $49.50
Equation: 4.50x + 3.50y = 49.50
Idk how to solve the equation but this should be the correct equation
To solve this problem, we can use the z statistic to find
for the probability. The formula for z score is:
z = (x – u) / s
Where,
u = the sample mean = 68
s = standard deviation of the samples = 12
x = sample value = 70
In this case, what is asked is the probability that the
sample mean is larger than 70, therefore this corresponds to the right of z on
the graph of normal distribution.
z = (70 – 68) / 12
z = 2 / 12
z = 0.17
Therefore finding for P at z ≥ 0.17 using the standard
distribution tables:
P (z = 0.17) = 0.5675
But this is not the answer yet since this is the P to the
left of z. Therefore the correct one is:
P (z ≥ 0.17) = 1 - 0.5675
P (z ≥ 0.17) = 0.4325 = 43.25%
<span>The probability that the sample mean is larger than 70 is
43.25%</span>
Here's what we'll be evaluating:
24 2/3 - 5/6 24 4/6 - 5/6 23 10/6-5/6 23 5/6
------------------- = -------------------- = -------------------- = ----------------------
11 pieces 11 pieces 11 pieces 11 [pieces
Now, this 23 5/6 is equivalent to 143/6, which we must divide by 11:
143 1
------ * ---------- = 13/6 (feet)
6 11
Each piece will be 13/6 ft long (2 1/6 ft).
Answer:
Step-by-step explanation: if Peytons base pay= $60 plus she earns commission on $x (computers sold)
P= $60+ (0.025x)
You would multiply by 0.025 as this equals 2.5%
Remember PEMDAS- parentheses, exponents, multiplications, division, addition, subtraction
