Answer:

It will take approximately 7 days to receive a package that is 224 miles away and weighs 2.2 pounds.

Step-by-step explanation:

Given : \widehat{y} =0.5 + 0.02x_1 + 0.85x_2

To Find : Use this equation to predict the how long it will take to receive a package that is 224 miles away and weighs 2.2 pounds.

Solution:

\widehat{y} =0.5 + 0.02x_1 + 0.85x_2

y denotes time

x_1 denotes distance to travel

x_2 denotes weight of package

Now x_1 =224

x_2=2.2

Substitute the values in the equation

\widehat{y} =0.5 + 0.02(224) + 0.85(2.2)

\widehat{y} =6.85

So, Time = 6.85 days

Hence  it will take approximately 7 days to receive a package that is 224 miles away and weighs 2.2 pounds.

Find the value for x. Round your answer to the nearest hundredth. Area of the triangle = 8 ft^2​
zmey [24]

Answer:

x = 3.51

Step-by-step explanation:

Since, formula to determine the area f a triangle is,

Area = \frac{1}{2}(\text{Base})(\text{Height})

     8 = \frac{1}{2}(x + 1)(3x - 7)

16 = x(3x - 7) + 1(3x - 7)

16 = 3x² - 7x + 3x - 7

16 = 3x² - 4x - 7

0 = 3x² - 4x - 23

3x²- 4x - 23 = 0

By quadratic formula,

x = \frac{-b\pm \sqrt{b^{2}-4ac}}{2a}

x = \frac{4\pm \sqrt{(-4)^{2}-4(3)(-23)}}{2(3)}

x = \frac{4\pm \sqrt{292}}{6}

x = \frac{4\pm 17.09}{6}

x = 3.51, -2.18

But the length of sides can't be negative.

Therefore, x = 3.51 will be the answer.

What number is between 3.16 and 3.17?
VladimirAG [237]
There are multiple answers to this question
Answers: 3.161, 3.162, 3.163, 3.164, 3.165, 3.166, 3.167, 3.168, 3.169
(You can just pick one)

Reason: just look at the place numbers. The number has to be between 3.16 and 3.17. So go to the next place value which is the thousandths place. 3.161-3.169 all are between since they have a 6 in the hundredths place, but does not go over 1.17

John has taken out a loan for college. He started paying off the loan with a first payment of $100. Each month he pays, he wants
sergeinik [125]
<span>Let a_0 = 100, the first payment. Every subsequent payment is the prior payment, times 1.1. In order to represent that, let a_n be the term in question. The term before it is a_n-1. So a_n = 1.1 * a_n-1. This means that a_19 = 1.1*a_18, a_18 = 1.1*a_17, etc. To find the sum of your first 20 payments, this sum is equal to a_0+a_1+a_2+...+a_19. a_1 = 1.1*a_0, so a_2 = 1.1*(1.1*a_0) = (1.1)^2 * a_0, a_3 = 1.1*a_2 = (1.1)^3*a_3, and so on. So the sum can be reduced to S = a_0 * (1+ 1.1 + 1.1^2 + 1.1^3 + ... + 1.1^19) which is approximately $5727.50</span>
