<u>Let's take this problem step-by-step</u>:

<u>Both problems involve triangles</u>:

⇒ let's find out the sum of the interior angle w/ formula 180(n-2)

<em> Total Interior Angle Sum of Triangle = 180(3-2) = 180</em>

<u>Let's solve the first problem (A)</u>

⇒ we know the total interior angle sum is 180 degrees

⇒ we know that two of the angles are 30 degrees and 90 degrees

* <em>any angle with a square on them is 90 degrees</em>

⇒ therefore:

30 + 90 + y = 180

120 + y= 180

y = 60

<u>Let's solve the second problem</u>:

⇒ the angle opposite the exterior angle, 120 degrees, is on a flat line

with it

⇒ therefore it is 60 degrees

⇒ two angles on a flat line equal 180 degrees

⇒ two angles are therefore 60 degrees

⇒ therefore:

60 + 60 + y = 180

120 + y = 180

y = 60

<u>Answer:</u>

<u>(A) y= 60</u>
<u>(B) y =60</u>

Answer:

y=60° b=60°

Step-by-step explanation:

the sum of all degrees of interior triangle is 180

in the first one, 30° and 90° have been given.(that small square represent 90°)

so 180°-90°-30°=60°

in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°

The weight of an adult swan is normally distributed with a mean of 26 pounds and a standard deviation of 7.2 pounds. A farmer ra

Snezhnost [94]

Let $X$ denote the random variable for the weight of a swan. Then each swan in the sample of 36 selected by the farmer can be assigned a weight denoted by $X_1,\ldots,X_{36}$ , each independently and identically distributed with distribution $X_i\sim\mathcal N(26,7.2)$ .

You want to find

$\mathbb P(X_1+\cdots+X_{36}>1000)=\mathbb P\left(\displaystyle\sum_{i=1}^{36}X_i>1000\right)$

Note that the left side is 36 times the average of the weights of the swans in the sample, i.e. the probability above is equivalent to

$\mathbb P\left(36\displaystyle\sum_{i=1}^{36}\frac{X_i}{36}>1000\right)=\mathbb P\left(\overline X>\dfrac{1000}{36}\right)$

Recall that if $X\sim\mathcal N(\mu,\sigma)$ , then the sampling distribution $\overline X=\displaystyle\sum_{i=1}^n\frac{X_i}n\sim\mathcal N\left(\mu,\dfrac\sigma{\sqrt n}\right)$ with $n$ being the size of the sample.

Transforming to the standard normal distribution, you have

$Z=\dfrac{\overline X-\mu_{\overline X}}{\sigma_{\overline X}}=\sqrt n\dfrac{\overline X-\mu}{\sigma}$

so that in this case,

$Z=6\dfrac{\overline X-26}{7.2}$

and the probability is equivalent to

$\mathbb P\left(\overline X>\dfrac{1000}{36}\right)=\mathbb P\left(6\dfrac{\overline X-26}{7.2}>6\dfrac{\frac{1000}{36}-26}{7.2}\right)$
$=\mathbb P(Z>1.481)\approx0.0693$

Consider the numbers 14.25 and 0.86.

klio [65]

Answer:

Part A

The given numbers are 14.25 and 0.86

By multiplying the two numbers, we have;

14.25 × 0.86 = 12.255

By adding the two numbers, we have;

14.25 + 0.86 = 15.11

Therefore, addition gives the greatest solution because one of the number is a fraction less than one

Part B

By dividing the two numbers (Dividing the larger number, 14.25 by the smaller number 0.86), we have 14.25/0.86 ≈ 16.57

Therefore, dividing the larger number by the smaller fraction gives a solution larger than the solution found in part A because the larger number multiplied by (1 - the inverse smaller fraction number) is larger than the value of the smaller (fraction) number
