1 answer:

5 0

=3x^6 +4x+3+3x^8+6x
Combine like terms
=3x^8+3x^6+(4x+6x)+3
=3x^8+3x^6+10x+3

C) 3x^8+3x^6+10x+3 is the answer.

Hope this helps! :)

help pls i have 7 of these question 100 points there is a part 2 to this question i will be making another one 100 points as wel

Answer:

$y=x$
$y=x-2$
$y=2x+10$
$y=5x$
$y=x+21$

Whenever finding a rule, figure out what x+1 relates to in terms of y (aka the slope). Also, figure out the y-intercept (0,y)

Example:

x+1 = y+2.

Slope: 2 ÷ 1 = 2.

The y-intercept is (0,9)

This would make the rule y=2x+9

Some sources report that the weights of full-term newborn babies in a certain town have a mean of 8 pounds and a standard devia

Elodia [21]

Answer:

0.682 is the probability that one newborn baby will have a weight within one standard deviation of the mean.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 8 pounds

Standard Deviation, σ = 0.6 pounds

We are given that the distribution of weights of full-term newborn babies is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(weight between 7.4 and 8.6 pounds)

$P(7.4 \leq x \leq 8.6) = P(\displaystyle\frac{7.4 - 8}{0.6} \leq z \leq \displaystyle\frac{8.6-8}{0.6}) = P(-1 \leq z \leq 1)\\\\= P(z \leq 1) - P(z < -1)\\= 0.841 - 0.159 = 0.682 = 68.2\%$

$P(7.4 \leq x \leq 8.6) = 6.82\%$

This could also be found with the empirical formula.

0.682 is the probability that one newborn baby will have a weight within 0.6 pounds of the mean.

Arte-miy333 [17]

Plotting the 4 points and doing visual inspection will tell us if the quadrilateral is a parallelogram. We can also do analytical techniques which are to determine the slope and the distance between the points. Doing either of these two will give us
B. Yes,TUVW quadrilateral s a parallelogram because there are two pairs of parallel sides.
