A bike rental company charges a $5 service fee and $1 per hour. If this situation is represented as a function, what would be th
Elenna [48]
Write as a function equation: where f(x) is the same as "y"

f(x) = 5 + 1x   ------  y = 1x + 5

Use:  y = mx + b  (Where m = slope and b is y intercept)

Slope is 1 and y intercept is +5 

Remember slope is rise over run so 1 can be written as 1 / 1 and interpreted as rise 1 and run 1 both in the positive direction.

What is y=-4/3x +6. y=2
Mekhanik [1.2K]

The given equation is:
[/tex]y=-\frac{4}{3}x+6 [/tex] and we need to evaluate this for y=2.
So, first step is to plug in 2 for y in the above equation. Therefore,

2=-\frac{4}{3} x+6
2*3=-\frac{4}{3} x*3+6*3 Multiply each sides by common denominator 3
6=-4x+18
6-18= -4x Subtract 18 from each sides.
-12=-4x
-\frac{12}{-4} =-\frac{4x}{-4}
So, x=3

Suppose a researcher is estimating the proportion of trees showing signs of disease in a local forest. They randomly sample 150
Serhud [2]

Answer:

0.167 - 1.96 \sqrt{\frac{0.167(1-0.167)}{150}}=0.107

0.167 + 1.96 \sqrt{\frac{0.167(1-0.167)}{150}}=0.227

And the 95% confidence interval would be given (0.107;0.227).

Step-by-step explanation:

Information given

X= 25 number of trees with signs of disease

n= 150 the sample selected

\hat p=\frac{25}{150}= 0.167 the proportion of trees with signs of disease

The confidence interval for the true proportion would be given by this formula

\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}

For the 95% confidence interval the significance is \alpha=1-0.95=0.05 and \alpha/2=0.025, and the critical value would be

z_{\alpha/2}=1.96

And replacing we got:

0.167 - 1.96 \sqrt{\frac{0.167(1-0.167)}{150}}=0.107

0.167 + 1.96 \sqrt{\frac{0.167(1-0.167)}{150}}=0.227

And the 95% confidence interval would be given (0.107;0.227).

The city plans to extend the Wildflower Tral to make it 2 ½ times its current length in the next 5 years. How long will the Wild
Sloan [31]

Answer: 5¹⁵/₁₆

Step-by-step explanation:

The Wildflower Trail is currently 2³/₈ miles long.

If the city will extend it by 2¹/₂ in 5 years, the length in five years will be;

= 2³/₈ * 2¹/₂

= 19/8 * 5/2

= 95/16

= 5¹⁵/₁₆
