The answer would be -36 because all i did is multiply -12 with 3 and you get -36.

hope this helped :)

X divided by 3 equal -12 can be written down as:

$\frac{x}{3}$ = -12 / * 3 (both sides)
x = -12 * 3
x = -36

I hope it will help you ;)

Complete Question

Suppose the weight of Chipotle burritos follows a normal distribution with mean of 450 grams, and variance of 100 grams2 . Define a random variable to be the weight of a randomly chosen burrito.

(a) What is the probability that a Chipotle burrito weighs less than 445 grams? (3 points)

(b) 20% of Chipotle burritos weigh more than what weight

Answer:

$P(X < 445 )= 0.3085$

$k = 458.42$

Step-by-step explanation:

From question we are told that

The population mean is $\mu = 450 \ g$

The variance is $var = 100 \ g^2$

The consider weight is $x = 445 \ g$

The standard deviation is mathematically represented as

$\sigma = \sqrt{var}$

substituting values

$\sigma = \sqrt{ 100}$

$\sigma = 10$

Given that weight of Chipotle burritos follows a normal distribution the the probability that a Chipotle burrito weighs less than x grams is mathematically represented as

$P(X < x ) = P ( \frac{X - \mu }{\sigma } < \frac{x - \mu }{\sigma } )$

Where $\frac{X - \mu }{\sigma }$ is equal to z (the standardized values of the random number X )

$P(X < x ) = P (Z < \frac{x - \mu }{\sigma } )$

substituting values

$P(X < 445 ) = P (Z < \frac{445 - 450 }{10} )$

$P(X < 445 ) = P (Z$

Now from the normal distribution table the value for $P (Z$ is

$P(X < 445 ) = P (Z$

=> $P(X < 445 )= 0.3085$

Let the probability of the Chipotle burritos weighting more that k be 20% so

$P(X > k ) = P ( \frac{X - \mu }{\sigma } > \frac{k - \mu }{\sigma } ) = 0.2$

=> $P (Z> \frac{k - \mu }{\sigma } ) = 0.2$

=> $P (Z> \frac{k - 450}{10 } ) = 0.2$

From the normal distribution table the value of z for $P (Z> \frac{k - \mu }{\sigma } ) = 0.2$ is

$z = 0.8416$

=> $\frac{k - 450}{10 } = 0.8416$

=> $k = 458.42$

Karen says every equilateral triangle is acute.is this true explain

goblinko [34]

Hey there!

An equilateral triangle is a triangle that has all equal sides and angles. All the angles in a triangle equal 180 degrees. All triangles have 3 angles. 180/3=60 Each angle in an equilateral triangle is equal to 60 degrees. Acute angles are less than 90 degrees, so: 60<90. This makes every equilateral triangle acute.

I hope this helps!
