Answer: 8x^2+4x+16
Step-by-step explanation:
8x^2 – 5x + 9 - (– 9x – 7 )
8x^2−5x+9+9x+7
8x^2+(−5x+9x)+(9+7)
8x^2+4x+16
Answer:
y = x - 3
y = -5x + 2
Step-by-step explanation: For y=x-3 the "missing" coefficient of x (m in the y=mx+b format) is an implied +1. So the slope is "up-one & over one." y-intercept is -3
y = -5x +2 The slope is -5 so "down 5 & over 1" on the graph, The y-intercept is +2
Given the data temperatures to be;
We would require the following to get the 98% confidence interval of the mean body temperature.
Mean, Standard deviation, sample size, Probability of a confidence interval of 98%.
Using a calculator, we can get the mean to be
The standard deviation would be derived to be;
The sample size can be gotten from the question to be;
The probability value of a 98% confidence interval is given to be 2.33
We can then derive the answer using the formula below;
We would substitute into the formula
ANSWER:
Answer:
The percent of increase is 32.43%.
Step-by-step explanation:
Take the difference of his new score and the old score.
37-25 = 12
To find the percent change, take that difference and divide it by the new score. Then multiply that answer by 100%.
12/37 = .3243
.3243 x 100% = 32.43%
