Find the distance between -3/4 and 1 3/4 on a number line. Write your answer as a fraction or mixed number in simplest form.
A fraction is a way to describe a part of a whole. The distance between -3/4 and 1 3/4 on a number line is 1 unit.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
What is a Mixed Fraction?A mixed fraction is a fraction that contains a whole number and a fraction whose denominator is greater than the numerator. A mixed fraction can be converted as,
2 1/2
= (2×2 + 1)/2
= 5/2
= 2.5
The distance between -3/4 and 1 3/4 on a number line is,
Distance = 1 3/4 - 3/4
= 7/4 - 3/4
= (7-3)/4
= 4/4 units
= 1 units
Hence, the distance between -3/4 and 1 3/4 on a number line is 1 unit.

Solving the for angle NMP. *
Answer:
50°
Step-by-step explanation:
Angle NMP is an angle that has its vertex on a point along the circumference of the circle, thus, angle NMP is referred to as an inscribed angle of the circle.
The measure of an inscribed angle is equal to half of the measure of the arc it intercepts.
Therefore, the following equation shows the relationship between inscribed angle NMP and arc NP:
m<NMP = ½ × measure of arc NP
m<NMP = ½*100
m<NMP = 50°

Answer:
Step-by-step explanation:
A plane took 1.5 hours to complete the journey of 915 miles.
Therefore, constant of proportionality will be,
k = [tex]\frac{915}{1.5}=610[/tex]
[tex]\frac{y}{x}=610[/tex]
y = 610x
Time in hours (x) Distance in miles (y) Constant [tex](\frac{y}{x})[/tex]
1 y = 610x ⇒ y = 610 miles 610
1.5 915 610
2 y = 2 × 610 = 1220 miles 610
2.5 y = 2.5 × 610 = 1525 miles 610

Given the function () 2x + 3x + 10. find f(1) and (3). Choose the statement that is true concerning these two values,
The value of t(1) is the same as the value of f(3).
The value of (1) cannot be compared to the value of (3)
The value of t(1) is larger than the value of (3)
The value of t(1) is smaller than the value of (3)
Answer:
The value of t(1) is smaller than the value of (3)
Step-by-step explanation:
Given function:
f(x) = 2x + 3x + 10
Insert the value x = 1 into the function:
f(1) = 2(1) + 3(1) + 10 = 5 + 10 = 15
Insert the value x = 3 into the function:
f(3) = 2(3) + 3(3) + 10 = 6 + 9 + 10 = 25
f(3) is larger than f(1)
Cindy’s square garden has a side length of x ft. She will plant 5 tulip bulbs per square foot. Write a function g to model the number of bulbs she will plant. Use your function to determine how many bulbs will she plant if the garden has a side length of 8 feet?
Answer:
The function that model the number of bulbs she will plant is g = 5x²
She will plant 320 bulbs in the garden
Step-by-step explanation:
∵ Cindy’s square garden has a side length of x ft
∵ Area of the square = side × side
∴ The area of the garden = x × x
∴ The area of the garden = x² ft²
∵ She will plant 5 tulip bulbs per square foot
→ That means there are 5 tulip bulbs in 1 foot²
∵ The area of the garden is x² ft²
→ Multiply the area of the garden by 5
∴ The number of tulip bulbs in the garden = 5 × x²
∴ The number of tulip bulbs in the garden = 5x²
∵ g represents the number of bulbs she will plant in her garden
∴ g = 5x²
∴ The function that model the number of bulbs she will plant is g = 5x²
∵ The garden has a side length of 8 feet
→ That means the value of x is 8 feet
∴ x = 8
→ Substitute the value of x in the function above
∴ g = 5(8)² = 5(64)
∴ g = 320
∴ She will plant 320 bulbs in the garden

how do I solve for 3(2x-1)+2x=4x-11
Answer:
x=-2
Step-by-step explanation:
3(2x-1)+2x=4x-11
6x-3+2x=4x-11
8x-3=4x-11
8x=4x-8
4x=-8
x=-2
The answer to the equation is [tex]x=-2[/tex]
First, you must use distributive property to simplify the equation.
[tex]6x-3+2x=4x-11[/tex]
Then, you must combine like terms.
[tex](6x+2x)-3=4x-11[/tex]
[tex]8x-3=4x=11[/tex]
Next, you must subtract 4x on each side
[tex]4x-3=-11[/tex]
Then, add 3 on both sides
[tex]4x=-8[/tex]
Finally, divide both sides by 4
[tex]\frac{4x}{4} =\frac{-8}{4}[/tex]
[tex]x=-2[/tex]
A satellite 200 miles above the earth is orbiting the earth once every 6 hours. How far does the satellite travel in 1 hour?
(Assume the radius of the earth is 4,000 miles.) Give your answer as both an exact value and an approximation to three significant digits
Answer:
The answer is below
Step-by-step explanation:
Speed is the ratio of total distance travelled to total time taken to cover distance.
The radius of the orbit = radius of earth + height of satellite from earth = 4000 miles + 200 miles = 4200 miles
The total distance around the orbit = perimeter of orbit = 2π(radius of orbit) = 2π(4200) = 8400π miles
[tex]Speed=\frac{distance \ traveled}{time\ taken} =\frac{8400\pi\ miles}{6\ hours} =1400\pi\ miles/hour\\\\Distance \ traveled\ in \ 1\ hour=1400\pi\ miles/hour*1\ hour=1400\pi\ miles=4398.23\ miles\\\\Distance=4398\ miles[/tex]

Actually Welcome to the Concept of the Statistics,
If we see here, The Andrew is working for 20 hours and his pay for 20hours is, $175
so for 1 hour, he gets = 175÷20 => $8.75 per hour
, so now after 1 year, his pay increases by $1.05 per hour, then we have to add this new amount of pay in his old amount, so that we can show that his pay is actually INCREASED, so the new pay is given as,
$8.75 + $1.05 (per hour)= $9.80
so now his total pay is given as,
E= 9.80h

Suppose that a sample of n students at the same university (instead of n) determines that % of the sample use the web browser. At the level of significance, is there evidence that the market share for the web browser at the university is greater than the worldwide market share of %?
Complete Question
The worldwide market share for a web browser was 20.5% in a recent month. Suppose that a sample of 200 random students at a certain university finds that 50 use the browser.
At the 0.05 level of significance, is there evidence that the market share for the web browser at the university is greater than the worldwide market share of 20.5%?
Answer:
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to show that the market share for the web browser at the university is greater than the worldwide market share of 20.5 %?
Step-by-step explanation:
From the question we are told that
The population proportion is [tex]p = 0.205[/tex]
The sample size is n = 200
The number that uses the browser is k = 50
The level of significance is [tex]\alpha = 0.05[/tex]
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{50}{200}[/tex]
=> [tex]\^ p = 0.250[/tex]
The null hypothesis is [tex]H_o : p = 0.205[/tex]
The alternative hypothesis is [tex]H_a : p > 0.205[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{ \^ p - p }{ \sqrt{ \frac{ p (1 - p )}{ n} } }[/tex]
=> [tex]z = \frac{ 0.250 - 0.205 }{ \sqrt{ \frac{ 0.205 (1 - 0.205 )}{ 200} } }[/tex]
=> [tex]z = 1.5764[/tex]
Generally the area under [tex]z = 1.5764[/tex] to the right is
[tex]p-value = P( Z > 1.5764 ) = 0.057467[/tex]
From the value we obtained we can see that the [tex]p-value > \alpha[/tex] hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to show that the market share for the web browser at the university is greater than the worldwide market share of 20.5 %?
