We can solve this problem using cross-multiplying method.
We have following information
18 points = 40%
We need to find out the final score. Let's use x for final number of points.
x points = 100%
We can write this:
18 points = 40%
x points = 100%
We cross multiply numbers
18*100=x*40
1800=40x /:40
1800/40=x
x=45
The final score was 45 points.
Answer:
a. Critical values : r = ±0.396, no significant linear correlation.
Step-by-step explanation:
The critical value is 0.396 and test statistic is 0.543. The null hypothesis is rejected or accepted on the basis of level of significance. When the p-value Test statistics is greater than level of significance we fail to reject the null hypothesis and null hypothesis is then accepted. In the given case test statistics value is greater than critical value then we should accept the null hypothesis.
Answer:
$776.59
Step-by-step explanation:
For this question, you must use the formula for being compounded continuously. A=Pe^r*t. A stands for your total balance, the part you are trying to find. P stands for the initial amount. E is a constant. R is the rate of interest. And t is the number of years taken. So, to fill in the formula: P is 550, t is 15, and R would be 0.023. For R, remember not to just take the percentage, you must divide the percent of interest by 100, so 2.3 by 100 to get to 0.023. The formula should know be A= (550) e^ (0.023)(15). plug that into your calculator, and you should get $776.59.
hope this helps!
