Answer:
<h2>
x=2</h2>
Step-by-step explanation:
Isolate x
3x + 4x - 8 = 6
+8 +8
3x + 4x = 6 + 8
Simplify
3x + 4x = 6 + 8
7x = 14
Divide both sides by 7
7x/7 = 14/7
x = 2
Answer:
0.5
Step-by-step explanation:
0.5 x 4 = 2, 2 + 7 = 9
Answer:
missing value b is 14
Step-by-step explanation:
We have been given the modulus of a complex number which is
Here on comparing the given complex number with general a+bi we get:
a=48 and b=b
On substituting the values in the formula for modulus we get:
Therefore, missing value b is 14
Answer: Prokhorova is more outstanding.
Step-by-step explanation: To compare scores from different distributions, first standardize it:
z-score =
where
x is the individual mean you want to compare
μ is the mean of the population
σ is standard deviation
For <u>Gertrud Bacher</u>:
z-score =
z-score = (s)
The negative sign indicates Bacher's mean is less than the mean
For <u>Yelena Prokhorova</u>:
z-score =
z-score = 2 (cm)
The positive sign indicates Prokhorova's mean is more than the mean.
Using z-score table, you determine the percentiles are:
For Bacher: Percentile = 5.5%
For Prokhorova: Percentile = 97.7%
Bacher's percentile means she is above 5.5% of the participants, while Prokhorova is 97.7% above the other competitors, which means Prokhorova have a better performance and deserves more points.
Answer:
start by mulitplying ten 5 times so 10x10x10x10x10=100,000. then multiply 100,000x3.8=380,000. and then times 300 so your ancwer is 114,000,000
Step-by-step explanation:hope it helps
