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
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!

f(x) = 2x² + x – 4
Find f(-10)
NEED IT FAST
Answer:
[tex]f(-10)=186[/tex]
Step-by-step explanation:
We can use substitution to find the value of [tex]f(-10)[/tex].
[tex]f(x) = 2x^2+x-4[/tex]
[tex]f(-10) = 2(-10)^2-10-4[/tex]
[tex]=200-10-4[/tex]
[tex]=186[/tex]
∴ [tex]f(-10) =186[/tex]
Hope this helps :)
Answer:
The value of f(-10) is equal to 186.
Step-by-step explanation:
We are given the function:
[tex]f(x) = 2x^2 + x - 4[/tex]
We are told to find the value of:
[tex]f(-10)[/tex]
If we pay close attention, we can see a transition between:
[tex]f(x) \rightarrow f(-10)[/tex]
We have turned x into -10, making x = -10.
Therefore, we can change the value of x in the entire function to -10.
[tex]f(-10)=2(-10)^2+(-10) - 4\\\\f(-10) = 200 - 10 - 4\\\\f(-10) = 186[/tex]
Therefore, f(-10) = 186.

Step-by-step explanation:
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.
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)

How many lines of symmetry does the following figure have?
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.

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!
