$\text{The scientific notation:}\\\\a\cdot10^k\ \text{where}\ 1\leq a$

$18.4\ m=1.84\cdot10\ m\\\\0.000000000172\ g=0\underbrace{.0000000001}_{10\to}72=1.72\cdot10^{-10}\ g\\\\4292000\ s=4\underbrace{292000}_{\leftarrow6}\ s=4.292\cdot10^6\ s\\\\8.3\ \cdot10^{-4}\ m\\\\1.496\cdot10^8\ m\\\\23.1\cdot10^{-3}\ kg=2.31\cdot10\cdot10^{-3}\ kg=2.31\cdot10^{-2}\ kg$

someone pls help!!! Complete the proofs using the most appropriate method. Some may require CPCTC. I will give brainly

Softa [21]

Answer:

#9

I can't write out the whole proof here.

it bisects, so we know BCA is congruent to DCA

abc being congruent to adc is given

AC = AC because it is a singular side

AAS

then the lines are congruent by CPCTC

Use the standard normal distribution or the t-distribution to construct a 99% confidence interval for the population mean. Jus

vichka [17]

Answer:

(25.732,30.868)

Step-by-step explanation:

Given that in a random sample of 42 people, the mean body mass index (BMI) was 28.3 and the standard deviation was 6.09.

Since only sample std deviation is known we can use only t distribution

Std error = $\frac{s}{\sqrt{n} } =\frac{6.09}{\sqrt{42} } \\=0.9397$

$df = 42-1 =41$

t critical for 99% two tailed $= 2.733$

Margin of error $= 2.733*0.9397=2.568$

Confidence interval lower bound = $28.3-2.568=25.732$

Upper bound = $28.3+2.568=30.868$

4. The following intervals were plausible population proportions for a given sample. Find the margin of error in each case.

Vedmedyk [2.9K]

Answer: a. 0.15 b. 0.03 c. 0.055 d. 0.05

Step-by-step explanation:

For plausible intervals of population proportions , the margin of error is basically half of the difference between upper limit and lower limit.

a. Interval = From 0.35 to 0.65

Upper limit = 0.65

Lower limit = 0.35

Difference = Upper limit- Lower limit

= 0.65-0.35=0.30

Margin of error = (Difference)÷2 =(0.30)÷2=0.15

b. Interval = From 0.72 to 0.78

Upper limit = 0.78

Lower limit = 0.72

Difference = 0.78-0.72 = 0.06

Margin of error =(0.06)÷2=0.03

c. Interval = From 0.84 to 0.95

Upper limit = 0.95

Lower limit = 0.84

Difference =0.95-0.84= 0.11

Margin of error = (0.11)÷2 = 0.055

d.Interval = From 0.47 to 0.57

Upper limit = 0.57

Lower limit = 0.47

Difference = 0.57-0.47=0.10

Margin of error = (0.10)÷2=0.05
