To a set of five grades with an average of 7.31, the following grades are added 4.47 and 9.15 What is the new average?
Answers
Answer:
New mean average of 7 grades = 7.17 (Approx.)
Step-by-step explanation:
Given:
Mean average of 5 grades = 7.31
Number of grades = 5
New grades = 4.47 and 9.15
Find:
New mean average of 7 grades
Computation:
Total of old grades = Mean average of 5 grades x Number of grades
Total of old grades = 7.31 x 5
Total of old grades = 36.55
Total of new grades = Total of old grades + 4.47 + 9.15
Total of new grades = 36.55 + 4.47 + 9.15
Total of new grades = 50.17
New mean average of 7 grades = 50.17 / 7
New mean average of 7 grades = 7.167
New mean average of 7 grades = 7.17 (Approx.)

If $520 is borrowed for 290 days at 2.15% simple annual interest, how much will be repaid at the end of 290
days?
Answers
Step-by-step explanation:
Formula for simple interest
[tex]a = p(1 + rt)[/tex]
where a = final amount
p = principal amount
r = annual interest rate
t = time in years
given p = 520,
r = 2.15/100
t = 290/365 (1 year = 365 days)
[tex]a = 520(1 + ( \frac{2.15}{100} )( \frac{290}{365} )) \\ = 520 (1 + \frac{1247}{73000} ) \\ = 520( \frac{74247}{73000} ) \\ = 528.88 \: (2.dp)[/tex]

The parallel line will have the same slope.
If you rearrange the above equation, you find ...
b = y - mx
For the given point and slope, the new y-intercept will be ...

A random sample of 8 cigarettes of a certain brand has an average nicotine content of 4.2 milligrams and a standard deviation of 1.4 milligrams. Is this in line with the manufacturer’s claim that the average nicotine content does not exceed 3.5 mg? Use a 0.01 level of significance and assume the distribution of nicotine contents to be normal.
Answers
Answer:
0.0793 > 0.01, which means that we have a result in line with the manufacturer's claim.
Step-by-step explanation:
Manufacturer’s claim that the average nicotine content does not exceed 3.5 mg
This means that the null hypothesis is given by:
[tex]H_{0}: \mu = 3.5[/tex]
And the alternate hypothesis is:
[tex]H_{a}: \mu > 3.5[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
3.5 is tested at the null hypothesis
This means that [tex]\mu = 3.5[/tex]
A random sample of 8 cigarettes of a certain brand has an average nicotine content of 4.2 milligrams and a standard deviation of 1.4 milligrams.
This means that [tex]n = 8, X = 4.2, \sigma = 1.4[/tex]
Value of the z-statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{4.2 - 3.5}{\frac{1.4}{\sqrt{8}}}[/tex]
[tex]z = 1.41[/tex]
Pvalue of the test:
We are testing if the mean is higher than 3.5.
The sample mean found is of 4.2, and we have to find the probability of finding a sample mean at least as large as this, which is 1 subtracted by the pvalue of z = 1.41.
z = 1.41 has a pvalue of 0.9207
1 - 0.9207 = 0.0793
0.0793 > 0.01, which means that we have a result in line with the manufacturer's claim.

2x² + 16x - 8 = 0
Yah, i plugged this into m a t h w a y
(all of ur questions pretty much can use this app or website)
Answer:
D
Step-by-step explanation:
Given
2x² + 16x - 8 = 0 ( divide through by 2 )
x² + 8x - 4 = 0 ( add 4 to both sides )
x² + 8x = 4
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(4)x + 16 = 4 + 16
(x + 4)² = 20 ( take the square root of both sides )
x + 4 = ± [tex]\sqrt{20}[/tex] = ± [tex]\sqrt{4(5)}[/tex] = ± 2[tex]\sqrt{5}[/tex] ( subtract 4 from both sides )
x = - 4 ± 2[tex]\sqrt{5}[/tex] → D

Answers
9514 1404 393
Answer:
48 minutes
Step-by-step explanation:
The average speed for stage 1 is ...
speed = distance/time = (110 mi)/(2 h) = 55 mi/h
Then the time for stage 2 is ...
time = distance/speed = (44 mi)/(55 mi/h) = (4/5 h)(60 min/h) = 48 min
The time for stage 2 is 48 minutes.
Answer:
Solution :-We know that
SpeeD = Distance/Time
Speed = 110/2
Speed = 55 mi/hr
For, 2
Speed = 44/55
Speed = 4/5
Speed = 48 min
