Answer:

Yes, they are eqivelant.

Step-by-step explanation:

5(1+2x) and 10x+5

The first step is to set them equal to each other, to see if they are equivelent.

5(1+2x) = 10x+5

Distribute the 5 to both terms in the parentheses by multiplying.

5(1) + 5(2x) = 10x +5

5 + 10x = 10x +5

The communative property of addition proves that these are equal.

A study of more than 3,000 toco toucans found that their weights were approximately Normally distributed, with a mean
ANTONII [103]

Using the normal distribution, it is found that the correct option is:

  • P(Y< 16) = 0.041. About 4.1% of all toco toucans weigh less than 16 ounces

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

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

  • It 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, which is the percentile of X.

In this problem:

  • Mean of 20 ounces, hence \mu = 20.
  • Standard deviation of 2.3 ounces, hence \sigma = 2.3

P(Y < 16) is the <u>p-value of Z when X = 16</u>, hence:

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

Z = \frac{16 - 20}{2.3}

Z = -1.74

Z = -1.74 has a p-value of 0.041.

This is valid for the entire population, hence, the correct interpretation is:

  • P(Y< 16) = 0.041. About 4.1% of all toco toucans weigh less than 16 ounces

WILL GIVE BRAINLIEST: If the graph of 2x+3y − 6=0 is perpendicular to the graph of ax − 3y=5. What is the value of a?
Ilya [14]

Answer:

a = \frac{9}{2}

Step-by-step explanation:

To find the value of a, find the Slope of both the equations.

For lines to be perpendicular to each other    m_{1}m_{2}  = - 1

For line 1:

2x + 3y − 6 = 0 represent the line in y=mx +c form

3y = -2x + 6

y = \frac{-2}{3} x + \frac{6}{3}

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

m_{1} = \frac{-2}{3}

For line 2:

ax - 3y = 5

ax = 5 + 3y

ax - 5 = 3y

y = \frac{ax}{3} - \frac{5}{3}

m_{2} = \frac{a}{3}

Apply the condition of perpendicularity:

\frac{-2}{3} * \frac{a}{3} = - 1

\frac{2a}{9} = 1

a = \frac{9}{2}

  • See the line is parallel to x axis.
  • The equation of that top is y<5

So

The range is

  • (-oo,0)U(oo,5)

So

  • -oo<y<5

Option D is correct
