Find the x-intercept of the line 2× +4y =8​

Mathematics

sertanlavr [38]3 years ago

Answer:

The x intercept is (4,0)

Step-by-step explanation:

2x +4y =8

To find the x intercept, we set y = 0 and solve for x

2x+4(0) = 8

2x= 8

Divide by 2

2x/2 = 8/2

x =4

The x intercept is (4,0)

Your cousin renews his apartment lease and pays a new monthly rent. His new rent is calculated by applying a discount of $50 to
nasty-shy [4]

Answer:

  • $1100

Step-by-step explanation:

Let the rent be x

<u>Discounted rent </u>

  • x - $50

<u>Increase applied</u>

  • 10%

<u>Final rent:</u>

  • (x - 50) + 10% = (x - 50)*1.1

<u>We know this is equal to x + 5% = 1.05x, comparing now</u>

  • 1.1(x - 50) = 1.05x
  • 1.1x - 1.05x = 55
  • 0.05x = 55
  • x = 55/0.05
  • x = $1100

A data set includes 103 body temperatures of healthy adult humans having a mean of 98.1 F and a standard deviation of 0.56 F. Co
Ira Lisetskai [31]

Answer:

The 99​% confidence interval estimate of the mean body temperature of all healthy humans is (97.955F, 98.245F).

98.6F is above the upper end of the interval, which means that the sample suggests that the mean body temperature could be lower than 98.6F.

Step-by-step explanation:

The first step is finding the confidence interval

The sample size is 103.

The first step to solve this problem is finding how many degrees of freedom there are, that is, the sample size subtracted by 1. So

df = 103-1 = 102

Then, we need to subtract one by the confidence level \alpha and divide by 2. So:

\frac{1-0.99}{2} = \frac{0.01}{2} = 0.005

Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 102 and 0.005 in the t-distribution table, we have T = 2.63.

Now, we need to find the standard deviation of the sample. That is:

s = \frac{0.56}{\sqrt{103}} = 0.055

Now, we multiply T and s

M = T*s = 2.63*0.055 = 0.145

For the lower end of the interval, we subtract the mean by M. So 98.1 - 0.145 = 97.955F.

For the upper end of the interval, we add the mean to M. So 98.1 + 0.145 = 98.245F.

The 99​% confidence interval estimate of the mean body temperature of all healthy humans is (97.955F, 98.245F).

98.6F is above the upper end of the interval, which means that the sample suggests that the mean body temperature could be lower than 98.6F.

Solve 5x+7 &gt; 17.<br> {x1x&lt;2}<br> O {XIX&gt; 2}<br> O {xIx&gt;-2}<br> O {x1x &lt; -2}
fgiga [73]

Answer:

The answer is x > 2

Step-by-step explanation:

to solve this inequality:

5x+7 > 17

Put "-7" on both sides

5x+10

divide by 5 on both sides

your answer should be 2.
