Which equation can we use to determine h, the number of hops it takes the rabbit to reach the plant?
Choose 1 answer:
Answers
Answer:
C
Step-by-step explanation:
He is already 4 m away from the burrow and the plant is 6 meters away the plant is the goal and each hop brings him 0.4 closer so you would multiply 0.4 by the amount of hops and add 4 and it should equal 6 ex: 4+0.4h=6
if you where to solve for h you would get the amount of hops you need. hope this was helpful :D

How many lines of symmetry does the following figure have?
Answers
In an equilateral triangle, the number of line of symmetry is three. Then the correct option is C.
What is the axes of symmetry?If a line intersect the shape and the shape look identical on both sides of line, then the line is known as axis of symmetry.
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
If all the sides of the triangle are congruent, then the triangle is known as an equilateral triangle.
And each angle of the equilateral triangle is 60 degrees.

A. (4,0)
B. (5,0)
C. (0,2)
D. (0,10)
Answers
Why:
Your given equation is 5x+2y=20, so in order to find the y-intercept, we must put it in slope-intercept form, a.k.a. y=max+b.
To do this, subtract 5x from both sides. This will then give you 2y=-5x+20.
And to fully simply, divide both sides by 2. Finally, you get y=(-5/2)x+10. And since we know b in slope-intercept form is the y-intercept, and 10 is b in our final function/equation. We get the answer of y-intercept=(0,10)

On day two of a study on body temperatures, 106 temperatures were taken. Suppose that we only have the first 10 temperatures to work with. The mean and standard deviation of these 10 scores were 98.44o F and 0.30o F, respectively. Construct a 95% confidence interval for the mean of all body temperatures.
Answers
Answer:
The 95% confidence interval = (98.225, 98.655)
Step-by-step explanation:
The formula for Confidence Interval =
Mean ± z × standard deviation/√n
Where Mean = 98.44°F
Standard deviation = 0.30°F
n = number of samples is 10
Because our number if samples is small, we use the t score confidence interval formula
Mean ± t × standard deviation/√n
Degrees of Freedom = n - 1
= 10 - 1 = 9
We find the t score of 95% confidence interval and degrees of freedom 9
= 2.262
Hence,
Confidence interval = 98.44 ± 2.262 × 0.30/√10
= 98.44 ± 0.214592162
Confidence Interval
98.44 - 0.214592162
= 98.225407838
≈ 98.225
98.44 + 0.214592162
= 98.654592162
≈ 98.655
The 95% confidence interval = (98.225, 98.655)
The 95% confidence interval for the mean of all body temperatures is [98.2255, 98.6545] (in degree Fahrenheit)
How to calculate confidence interval for population mean from small sample?If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.
Let the sample mean given as [tex]\overline{x}[/tex] andThe sample standard deviation s, andThe sample size = n, and The level of significance = [tex]\alpha[/tex]Then, we get the confidence interval in between the limits
[tex]\overline{x} \pm t_{\alpha/2}\times \dfrac{s}{\sqrt{n}}[/tex]
where [tex]t_{\alpha/2}[/tex] is the critical value of 't' that can be found online or from tabulated values of critical value for specific level of significance and degree of freedom = n - 1
For this case, we have:
The sample mean given as [tex]\overline{x}[/tex] = 98.44° FThe sample standard deviation s = 0.30° F, andThe sample size = n = 10, and The level of significance = [tex]\alpha[/tex] = 100% - confidence level = 100% - 95% = 5% = 0.05The degree of freedom(d.f.) is n-1 = 10-1=9
At d.f. 9, at level of significance 0.05, the critical value of t is [tex]t_{\alpha/2} = 2.262[/tex]
Thus, the limits of the confidence interval is calculated as;
[tex]\overline{x} \pm t_{\alpha/2}\times \dfrac{s}{\sqrt{n}} = 98.44 \pm 2.262 \times \dfrac{0.3}{\sqrt{10}} = 98.44 \pm 0.2145[/tex]
This shows that the confidence interval is [98.44 - 0.2145, 98.44 + 0.2145] which is [98.2255, 98.6545] (in degree Fahrenheit)
Thus, the 95% confidence interval for the mean of all body temperatures is [98.2255, 98.6545] (in degree Fahrenheit)

Answer: The y-intercept is 3. The slope is 1.
Step-by-step explanation: Since the y coordinate is intercepting the y axis, the y-intercept is 3. To find the slope, the formula is change of y over change of x. The coordinates on this plane is (0,3) and (-3,0). That means the equation is (3-0) divided by (0-(-3)). That equals 3 divided by 3 which is obviously 1. Mark Brainliest plz!

Which unit rate is equivalent to 15 miles per gallon?
thirty miles over three gallons
three gallons over thirty miles
four gallons over sixty miles
sixty miles over four gallons
Answers
Answer:
sixty miles over four gallons
Step-by-step explanation:
The “over” word means divide, so let’s change all of these choices into expressions and evaluate them:
thirty miles over three gallons -> 30 mi/3 gal = 10 mi/gal
three gallons over thirty miles -> 3 gal/30mi = 1 gal/10 mi = 0.1 gal/mi (because it is asking for unit rate)
four gallons over sixty miles -> 4 gal/60 mi = 15 gal/mi
sixty miles over four gallons -> 60 mi/4 gal = 15 mi/gal
The problem is asking for which unit rate is equivalent to 15 mi/gal. We see that this fits the last choice (the value and the units). Therefore, the last choice is our answer.
I hope this helps! :)
Answer:
Step-by-step explanation:
It is asking you what is equal if 1g= 15miles.
If 1g=15 miles,
then 2g=30 miles,
3g=45miles,
and etc.
Each gallon can drive for 15 miles, so multiplying the number of gallons by 15 will tell you how many miles that person can drive.
Ex. 1x15=15 miles,
2x15=30 miles
3x15= 45 miles
Hope this helps!
