A fish was at the river-bed at a certain time. After 5 minutes, the water level of the river rose
up 2.4 cm and the water level of the river rose up again 3½cm after 4 minutes. The moment, the fish was at 14.6 cm from the river-bed and 162 cm below water level of the river.
Calculate the original height, in cm, of the water level of the river.
Answers
Answer:
170.7 cmStep-by-step explanation:
Let the original water level is x.
Use below equation to find its value:
x + 2.4 + 3 1/2 = 162 + 14.6x + 2.4 + 3.5 = 176.6x + 5.9 = 176.6x = 176.6 - 5.9x = 170.7 cmPlease help me with this,I will give you brainliest (only if you anwser first)

A salesman who is on the road visiting clients thinks that, on average, he drives the same distance each day of the week. He keeps track of his mileage for several weeks and discovers that he averages 122 miles on Mon- days, 203 miles on Tuesdays, 176 miles on Wednesdays, 181 miles on Thursdays, and 108 miles on Fridays. He wonders if this evidence contradicts his belief in a uni- form distribution of miles across the days of the week. Explain why it is not appropriate to test his hypothesis using the chi-square goodness-of-fit test.
Answers
Answer:
The conditions are not met.
Step-by-step explanation:
The conditions for the chi square test for goodness of fit are
1) the sample is a random sample
2) the variable under study is categorical
3) all expected value of the number of sample observations are greater or equal to 5.
A)The observations must be independent
B) for 2 categories the expected values must be at least 5
C) for the 3 categories the expected values must be at least 1 and no more than 20% may be smaller than 5
The observations given may not be independent i.e have equal chances of occurrences or are maybe dependent on each other in the sense that there maybe a limit for his traveling mileage or the a limit for petrol ( fuel ) usage . So if he is required to drive 500 miles in a week each day mileage depends on the other day mileage .
Also we are given the information that keeps track of his mileage for several weeks, but we are not sure if several refers to more than 5 .
As both conditions are not clearly satisfied it is not appropriate to test his hypothesis using the chi-square goodness-of-fit test.
The sample must also be a random sample.
Here he has taken the mean of all the days.

What is the value of 2x^2+6x-9 when x = 3
Answers
Answer:
45
Step-by-step explanation:
We have the equation 2x² + 6x + 9 and are asked to find the value when x =3.
To solve this, all we need to do is substitute all variables with "x" to 3. Then do the properties :
2x² + 6x + 9
2(3)² + 6(3) + 9
Do exponents first :
2(9) + 6(3) + 9
Now multiply the numbers with parenthesis next to them :
18 + 18 + 9
Add to get the answer :
45
Answer:
27
Step-by-step explanation:
We have the equation:
2x^2+6x-9
If x = 3, we can substitute 3 in for the x values.
We get the equation:
2([tex]3^{2}[/tex]) + 6(3) - 9
Using PEMDAS:
First, evaluate the power.
3^2 = 9
Then, multiply the numbers.
2 x 9 + 6 x 3 - 9
We get:
18 + 18 - 9
Simplify.
18 + 18 = 36
36 - 9 = 27
Hope this helps.

You rent an apartment that costs $1800 per month during the first year, but the rent
is set to go up 11.5% per year.
What would be the rent of the apartment during the
10th
year of living in the apartment? Round to the nearest tenth (if necessary).
Answers
Answer:
Rent in 10th year = $5345.90
Step-by-step explanation:
Rent of apartment during first year = $1800 per month
But growth in rent with 11.5% per year will be represented by the exponential function,
Rent in 't'th year = [tex]\text{Initial rent}(1+\frac{\text{Growth rate}}{100})^{\text{time}}[/tex]
= [tex]1800(1+\frac{11.5}{100})^t[/tex]
= [tex]1800(1.115)^t[/tex]
Therefore, rent during 10th year will be,
Rent in 10th year = [tex]1800(1.115)^{10}[/tex]
= $5345.90
