Answer:

For #1 a real life problem that could use this information would be "If a mud wall is built 24 feet high, and rain reduces the height by 6 feet every year, how long will it take the wall to disappear altogether?".

Step-by-step explanation:

When designing a problem like this when we already know the answer, use the y-intercept as a starting point. In this case, we start with a 24 foot wall.

Next use the rate as what changes for every unit. In this case, the height changes every year by -6.

Finally, the answer should always be the x-intercept.

EleoNora [17]

From 2010 year to 2015 year 5 years passed, then t is equal to 5.
To find how many people attended the festival in 2015 we have to calculate y(5):
$y(5)=180,000(1.2)^{5}=180,000*2.48832=447,898$
Answer: 447,898 p. attanded festival in 2015

The ratio of female birds to male birds in a habitat is 2.4 to 1. If there are 123 female birds in the habitat, and approximatel

dusya [7]

So you will first need to divide 123 by 2.4 to get how many male birds are there. Then you need to multiply that answer by 0.4. That will be your final answer.

Answer:

3x + 1 = x + 5

2x + 1 = 5

2x = 4

x = 2

y = 3(2) + 1 = 6 + 1 = 7

A shipping company claims that 90% of its packages are delivered on time. Jenny noticed that out of the last 10 packages shipped

Gnoma [55]

Answer:

The probability is;

0.0000003645

Step-by-step explanation:

The probability of packages being early p is 90% = 0.9

The probability of packages being late q will be 1-p = 1-0.9 = 0.1

So the probability of 2 out of 10 random late will be subject to Bernoulli approximation of the Binomial theorem

That will be;

P(X = 2) = 10 C 2 0.9^2 0.1^8

= 0.0000003645

4 - 2(x-4)/ 3= 3(2x+5)/2<br>linear equation in one variable<br>no spamms❌❌❌❌

xxMikexx [17]

Step-by-step explanation:

4-2x+8/3 = 6x+15/2

12-2x+8/3= 6x+15/2 ( taken LCM. of 1,3,3 in LHS)

20-2x/3=6x+15/2

Do cross multiplication

2(20-2x) = 3(6x+15)

40-4x=18x+45

-4x-18x=45+40

-22x= 85

-x= 85/22

x= - 3.86..

hope it helps
