<h3>Write two division expression s that have the same vaule as 36.8 ÷ 2.3 </h3>

$32 \div 2 = 16\\\\48 \div 3 = 16$

Solution:

Given that,

We hve to find the two division expression s that have the same vaule as 36.8 ÷ 2.3

From given,

$36.8 \div 2.3 = 16$

So, we have to find two division expressions that has a value of 16

First division expression

We know that 32 divided by 2 gives 16

Thus, we can write as,

$32 \div 2 = 16$

Second Expression:

We know that 48 divided by 3 gives 16

Thus, we can write as,

$48 \div 3 = 16$

Thus the two expressions are found

Find the upper 20%of the weight?

meriva

Answer:

The upper 20% of the weighs are weights of at least X, which is $X = 0.84\sigma + \mu$ , in which $\sigma$ is the standard deviation of all weights and $\mu$ is the mean.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Upper 20% of weights:

The upper 20% of the weighs are weighs of at least X, which is found when Z has a p-value of 0.8. So X when Z = 0.84. Then

$Z = \frac{X - \mu}{\sigma}$

$0.84 = \frac{X - \mu}{\sigma}$

$X = 0.84\sigma + \mu$

The upper 20% of the weighs are weights of at least X, which is $X = 0.84\sigma + \mu$ , in which $\sigma$ is the standard deviation of all weights and $\mu$ is the mean.

Can someone pls help me

olga55 [171]

32-20 = 12

14-2 = 12

so the input is 12 more than the output

so 6+12 = 18

and

-10-12 = -22

Coefficient of b in expansion of (3+b)^4

Margarita [4]

Are you sure you want ONLY the coefficient of b? If you expand this, you will have b in 3 of 4 terms.

According to Pascal's Triangle, the coefficients of (a+b)^4 are as follows:

1
1 2 1
1 3 3 1
1 4 6 4 1

So (a+b)^4 would be 1a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + b^4

Here, you want (3 + b)^4. Here's what that looks like:

3^4 + 4[3^3*b] + 6[3^2*b^2] + 4[3*b^3] + 1[b^4]

Which coeff did you want?
