Answer 1

Answer:

Answer:

X=60

m<QRS= 90

Step-by-step explanation:

assuming that it all adds up to 180

Add all like terms:

50+10+1/2x=180

1/2x+60=180

-60-60

1/2x= 120

÷1/2= ÷1/2

x= 60

1.1/2(60)+10

Golf-course designers have become concerned that old courses are becoming obsolete since new technology has given golfers the ability to hit the ball so far. Designers, therefore, have proposed that new golf courses need to be built expecting that the average golfer can hit the ball more than 230 yards on average. A random sample of 177 golfers show that their mean driving distance is 230.7 yards, with a standard deviation of 41.8.1. Set up the null and alternative hypotheses to test for the designers belief.a. H0 : µ ≥ 230 versus Ha : µ < 230b. H0 : µ = 230.7 versus Ha : µ ≠ 230.7c. H0 : µ ≥ 230.7 versus Ha : µ < 230.7d.

In a clinical trial of 2165 subjects treated with a certain drug, 21 reported headaches. In a control group of 1718 subjects given a placebo, 23 reported headaches. Denoting the proportion of headaches in the treatment group by pt and denoting the proportion of headaches in the control (placebo) group by pc, the relative risk is pt/pc. The relative risk is a measure of the strength of the effect of the drug treatment. Another such measure is the odds ratio, which is the ratio of the odds in favor of a headache for the treatment group to the odds in favor of a headache for the control (placebo) group, found by evaluating StartFraction p Subscript t Baseline divided by (1 minus p Subscript t Baseline )Over p Subscript c Baseline divided by (1 minus p Subscript c Baseline )EndFraction . The relative risk and odds ratios are commonly used in medicine and epidemiological studies. Find the relative risk and odds ratio for the headache data. What do the results suggest about the risk of a headache from the drug treatment?
Which descriptions of a histogram are true? Check all that apply..A peak is a bar that is lower than the other bars around it. A peak is where the frequency is lowest. A peak is where the frequency is the highest. A cluster is a group of bars, meaning the frequency is higher in these intervals. A peak is a bar that is higher than the other bars around it. Intervals on a histogram where there are no bars mean the frequency is 0. If the graph is symmetrical, the data is clustered toward the right side. If the graph is symmetrical, the data is evenly distributed.

Use the product rule to calculate the derivatives of
( ax² + bx + c ) ( cx + d )

Answers

$\n \sf\longmapsto (d)/(dx)(ax^2+bx+c)(cx+d)$

$\boxed{\sf (d)/(dx)f(x).g(x)=f(x)(d)/(dx)g(x)+g(x)(d)/(dx)f(x)}$

c and d are constants

$\n \sf\longmapsto (ax^2+bx+c)(d)/(dx)(cx+d)+(cx+d)(d)/(dx)(ax^2+bx+c)$

$\n \sf\longmapsto (ax^2+bx+c)(c)+(cx+d)(2ax+b)$

$\n \sf\longmapsto acx^2+bcx+c^2+2acx^2+bcx+2adx+bd$

$\n \sf\longmapsto 3acx^2+2bcx+2adx+bd+c^2$

Answer:

• Product rule is as below:

${ \boxed{ \tt{ \: (dy)/(dx) = { \huge{v}} (du)/(dx) + { \huge{u}} (dv)/(dx) }}} \n$

u is (ax² + bx + c)
v is (cx + d)
du/dx is 2ax + bx
dv/dx is c

$\hookrightarrow \: { \rm{ (dy)/(dx) = (cx + d)(2ax + b) + (ax {}^(2) + bx + c)(c) }} \n \n { \rm{ (dy)/(dx) = (2ac {x}^(2) + bcx + 2adx + db) + (ac {x}^(2) + bcx + {c}^(2) )}} \n \n { \boxed{ \rm{ (dy)/(dx) = 3ac {x}^(2) + \{2bcx + 2adx \}x + (db + {c}^(2)) }}}$

A cell phone company charges $15 for 120 minutes. What is the cost per minute? Round to the nearest cent.

Answers

Answer: The cost per minute is $0.13 or 13 cents.

Step-by-step explanation:

If it charges $15 for 120 minutes then to get to one minute we will have to divide it by 120.

so 15/120 = 0.125 which rounds to 0.13 to the nearest cent.
