Keywords

transformed function, translation, rule

In this problem we have

$f(x)=|x+3|$

we know that

If the translation is $5$ units down

then

the rule of the translation is equal to

$(x,y)-------> (x,y-5)$

therefore

the answer is

the equation of the transformed function is equal to

$g(x)=|x+3|-5$

see the attached figure to better understand the problem

assume that 2000 births are randomly selected and 64 of the births are girls. use subjective judgment to describe the number of

tatuchka [14]

Total no. of births = 2000

Births of girls = 64

Birth% of girls

$= \frac{64}{2000} \times 100$

$= \frac{64}{20}$

$= \frac{6.4}{2}$

$= 3.2\%$

Hence, the number of girls are significantly low.

If a pentagon is regular, then all of the sides are the same length. This means that

$5x-4=2x+11 \iff 5x-2x = 11+4 \iff 3x=15 \iff x = 5$

So, if $x=5$ , the lengths of the sides evaluate to

$5x-4 = 25-4=21,\quad 2x+11=10+11=21$

So, all the sides of the pentagon are 21 units long, and AB is 21 units long as well, because all sides are the same length.

julia is putting together bag of 45 blocks. if she wants the probability of choosing a red block to be 1/5 how many red blocks j

4vir4ik [10]

Answer:

Step-by-step explanation:

Given that the sample size is 45 blocks

Let number of red blocks in the bag to be x

Then the probability of chosing a red block will be x/45

Given that the probability of choosing a red block is 1/5 then you can form the expression;

x/45 = 1/5 ---------------find the value of x by performing cross multiplication

5x=45*1

5x/5=45/5

x=9

Answer

Julia put 9 red blocks in the bag.

Merta reports that 74% of its trains are on time. A check of 60 randomly selected trains shows that 38 of them arrived on time.

kenny6666 [7]

Answer:

No, the on-time rate of 74% is not correct.

Solution:

As per the question:

Sample size, n = 60

The proportion of the population, P' = 74% = 0.74

q' = 1 - 0.74 = 0.26

We need to find the probability that out of 60 trains, 38 or lesser trains arrive on time.

Now,

The proportion of the given sample, p = $\frac{38}{60} = 0.634$

Therefore, the probability is given by:

$P(p\leq 0.634) = [\frac{p - P'}{\sqrt{\frac{P'q'}{n}}}]\leq [\frac{0.634 - 0.74}{\sqrt{\frac{0.74\times 0.26}{60}}}]$

P $(p\leq 0.634) = P[z\leq -1.87188]$

P $(p\leq 0.634) = P[z\leq -1.87] = 0.0298$

Therefore, Probability of the 38 or lesser trains out of 60 trains to be on time is 0.0298 or 2.98 %

Thus the on-time rate of 74% is incorrect.
