There are conversion tables everywhere that assist you in changing a different unit into another. Depending on what it is, you can also compare weight into water, cm into m and backwards.
Answer:
x = -3/2
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x+2(3x−7))=22x−65
Step 1: Simplify both sides of the equation.
4(x+2(3x−7))=22x−65
(4)(x)+(4)(2(3x−7))=22x+−65(Distribute)
4x+24x+−56=22x+−65
(4x+24x)+(−56)=22x−65(Combine Like Terms)
28x+−56=22x−65
28x−56=22x−65
Step 2: Subtract 22x from both sides.
28x−56−22x=22x−65−22x
6x−56=−65
Step 3: Add 56 to both sides.
6x−56+56=−65+56
6x=−9
Step 4: Divide both sides by 6.
6x = -9
6 6
x = -3/2
Answer:
C. - 4x^2 + 5x - 4
Step-by-step explanation:
just expand the equation and you'll get C
ST/VT = UT/WT6+14/14 = (x+4)+21/21X= 20*21/14 - 21x=420/14-25X=30-25x=5
The appropriate statistical procedure to use here is a two-tailed hypothesis test for the population mean
What is standard deviation?
- The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean.
- A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Explanation:
- Since we are interested in comparing here the mean heart rate for Canadians who participated in this fitness program, to that of the national average,
- We have to have to conduct a hypothesis test here for sample mean
- Since we are not trying to find the true population mean based on the sample mean, we do not have to construct a confidence interval
- As the sample size, n = 26 < 30,therefore we will use the t-test instead of the z-test.
Therefore, A one-sample t-test for means' is the correct choice.
