Answer:
-3° C < 1°C is the correct option.
Step-by-step explanation:
As we know that:
The inequality symbol '<' means 'less than'.The inequality symbol '>' means 'more than'.If someone says that something is cooler than the other thing, it indicates that it is lesser than the other based on its temperature.
As the ice cream at −3°C is cooler than ice cream at 1°C, it indicates that temperature -3° C < temperature 1°C.
Therefore, -3° C < 1°C is the correct option.

a point on a perpendicular bisector is 7cm from each endpoint of the bisected segment and 5cm from the point of intersection. What is the length of the segment?
9514 1404 393
Answer:
about 9.80 cm
Step-by-step explanation:
The length of half the segment (h) can be found from the Pythagorean theorem:
h² +5² = 7²
h² = 7² -5² = 49 -25 = 24
h = √24 = 2√6
This is half the segment length, so the whole segment length is ...
L = 2h = 2(2√6)
L = 4√6 ≈ 9.7980
The length of the segment is 4√6 ≈ 9.80 cm.

What is the answer to this question.
Fen completed a triathlon race whose total distance is DDD kilometers. First, she swam a distance of 0.50.50, point, 5 kilometer. Then, she rode a bicycle for xxx hours at an average speed of 202020 kilometers per hour. Finally, she ran for 0.50.50, point, 5 hour at an average speed of vvv kilometers per hour. Write an equation that relates DDD, xxx, and vvv.
Answer:
D = 0.5 + 20x + 0.5v
Step-by-step explanation:
Initial distance covered d1 = 0.5km
If she rode a bicycle for x hours at an average speed of 20 kilometers per hour, then her distance during thus period is,;
Speed = Distance/Time
Distance d2 = speed × time
d2 = 20x
If she ran for 0.5 hour at an average speed of v kilometers per hour, her distance this time will be;
Distance d3 = 0.5v
If her total distance is D, then;
D = d1+d2+d3
D = 0.5 + 20x + 0.5v
Hence an equation that relates D, x, and v is D = 0.5 + 20x + 0.5v
Alice’s Athletic Arena requires members to pay $20 to join and members must pay $1.50 for each time they come to work out. Roy’s Romper Room requires members to pay $5 to join and members must pay $4 for each time they come to work out. How many visits will it take for the costs to both be the same?
Answer:
6 visits will it take for the costs to be the same
Step-by-step explanation:
The form of the linear relation is y = m x + b, where
m is the rate of changeb is the initial amountAssume that the number of visits is x, and the total cost is y
∵ Alice’s Athletic Arena requires members to pay $20 to join
→ That means there is an initial amount of $20
∴ b = 20
∵ The members must pay $1.50 for each time they come to work out
→ That means there is a cost for every visit (rate of change)
∴ m = 1.5 dollars/visit
∵ The number of visits = x
∵ The total cost is y
→ Form the linear equation for this situation
∴ y = 1.5x + 20 ⇒ (1)
∵ Roy’s Romper Room requires members to pay $5 to join
∴ b = 5
∵ The members must pay $4 for each time they come to work out
∴ m = 4 dollar/visit
→ Form the linear equation for this situation
∴ y = 4x + 5 ⇒ (2)
∵ The costs to both are the same
→ That means, equate the right sides of (1) and (2)
∴ 1.5x + 20 = 4x + 5
→ Subtract 20 from both sides
∴ 1.5x + 20 - 20 = 4x + 5 - 20
∴ 1.5x = 4x - 15
→ Subtract 4x from both sides
∵ 1.5x - 4x = 4x - 4x - 15
∴ -2.5x = -15
→ Divide both sides by -2.5
∴ x = 6
∴ 6 visits will it take for the costs to be the same

Write the number three-hundred-sixty-five-thousandths in standard form.
Answer:
365/1,000 or .365
Step-by-step explanation:
HTH :)
Three hundred sixty five thousand in standard form is 365000.
What is standard form and word form of numbers ?The standard form of numbers is when we have to write the number in digits according to it's place and face value.
Word form of numbers is that when we have to write numbers given in numerical form to words by determining place and face value.
According to the given question we have to write three thousand sixty five thousand in standard form.
We know thousand has three zeroes.Suppose we have to write one thousand in standard form which is 1000.
Given we have to write three hundred sixty five thousand in standard form which is 365000.

1) (5x - 4)(x - 5) = 0
Answer: The answer is 1.5
Step-by-step explanation: First you want to add 5x + x which equals 6x. Then you want to add -5+-4 which = -9. Then you add 9 to the -9 to get rid of it. But you have to do it on both sides so you add 9+0 which =9. Finally you divide 9 by 6 which equals 1.5

It costs $4 to sign up for a music download service and $0.50 to download each song. Jada signs up for the service
and begins downloading music.
1. Complete the table showing how Jada can spend money downloading songs.
Step-by-step explanation:
Note: I could not find any attached table of values, however, we can make do with the information given
step one:
the cost of sign up = $4
the cost of download for each song= $0.5
Step two:
Required
we want to find the cost of downloading any number of songs.
let the number of songs be x
and let the total cost be y
Hence the cost function is
y=0.5x+4
now supposing the value of x which is the number of downloads from the table is 10, then the total cost for 10 downloads will be
y=0.5(10)+4
y=5+4
y=9
Hence it will cost $9 to download 10 songs, just plug in the value of x into the cost function
The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 77% of all fatally injured automobile drivers were intoxicated. A random sample of 55 records of automobile driver fatalities in a certain county showed that 34 involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than 77% in Kit Carson County? Use α = 0.01. Solve the problem using both the critical region method and the P-value method. Since the sampling distribution of is the normal distribution, you can use critical values from the standard normal distribution (Round any intermediate calculations to at least four decimal places. Round the test statistic and critical value to two decimal places. Round the P-value to four decimal places.)
Solution :
Population proportion, P = 77%
Sample size is given by n = 55
Sample proportion = [tex]$\frac{x}{n} = \frac{34}{55}= 0.61$[/tex]
Null hypothesis
The population proportion of the fatalities of the drivers that are related to alcohol = 77%
[tex]$H_0 : P = 77$[/tex] %
[tex]$H_0 : P = 0.77$[/tex]
Alternate hypothesis, [tex]$H_a : P < 0.77$[/tex]
Therefore, the test statistics = [tex]$\frac{0.61 - 0.77}{\sqrt{\frac{0.7 \times 0.23}{55}}}$[/tex]
= -3.2
Critical value = -1.64
and the rejection zone : test zone, -1.645
Therefore, we fail rejecting [tex]$H_0$[/tex]
p value 0.0582
rejection zone :: p value , 0.01
So we fail to reject [tex]$H_0$[/tex]
Thus the data does not indicate the population proportion of the drivers fatalities which are related to the alcohols which is less than 77% in the county of Kit Carson.
This month the Middle School Media newspaper has 25 pages. Twenty-five schools order the paper for each of their students. Each of the schools has 25 classrooms with 25 students in each classroom. What expression with an exponent shows the total number of pages in all of the newspapers?
Answer:
25^4
Step-by-step explanation:
Here, we want to find the expression that shows the total number of pages in all of the news papers
Number of pages per book = 25
Number of schools is 25
Number of classrooms is 25
Number of students per classroom is 25
Now; the number of students in each school
is 25 * 25
Number of students in all of the school will be;
25 * 25 * 25
So the number of pages in all of the schools will be;
25 * 25 * 25 * 25 = 25^4
