You do multiplication first
12765 times 6748=86138220
then add
86138220+6789=86145009

Every calculation with multiple operations must abide to BODMAS (Brackets, Other, Divide, Multiple, Addition, Subtraction)

Thus we would multiple first, giving us 86138220. Then we would add giving us: 86145009

As the sample size becomes larger, the sampling distribution of the sample mean approaches a _____. a. binomial distribution b.

kkurt [141]

Answer:

c. normal probability distribution

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

In this question:

By the Central Limit Theorem, it is a normal distribution, so option c.

Answer:

Option B) $\frac{1}{6}$ Inches

Step-by-step explanation:

Maria's Centipede = $1\frac{1}{12}$ inches = $\frac{13}{12}$ inches

Jerome Centipede = $\frac{11}{12}$

To see how much longer Maria's centipede was than Jerome's, we'll subtract the two:

=> $\frac{13}{12} -\frac{11}{12}$

=> $\frac{13-11}{12}$

=> $\frac{2}{12}$ inches

=> $\frac{1}{6}$ Inches

Consider the graph shown.

otez555 [7]

Answer:

y = $\frac{2}{3}$ x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, 4)

m = $\frac{4-2}{3-0}$ = $\frac{2}{3}$

The line crosses the y- axis at (0, 2) ⇒ c = 2

y = $\frac{2}{3}$ x + 2 ← equation of line

Which congruency theorem can be used to prove that ABD =DCA?

Dimas [21]

Answer:

The answer is "SAS".

Step-by-step explanation:

In this question we assume two angle is given that are:

$\ Two \ triangles \angle ABD \ and \angleDCA \\\\\ In \ this \ on \ angle \ is \ common \ that \ is, \\\\ AD=AD \\\\AB= CD \\\\\angle A \ is \ equal \ = \angle A \ (\ which \ is \ given)\\\\$

That's why SAS rule is correct.
