Find the distance between the pair of points (2, 3) and (6, 8)
Answers
Answer: d=sqrt(41) =6.4031
Step-by-step explanation:
We know that the distance between the two points (x 1 ,y 1 ) and (x 2 ,y 2 ) is
d= sqrt((x2-x1)^2 +(y2-y1)^2 )
as given
x1=2 ,x2=6 ,y1=3 ,y2=8
d=sqrt((6-2)^2+(8-3)^2 )
d= sqrt((4)^2+(5)^2
d=sqrt(16+25)
d=sqrt(41) =6.4031

Malala is following this recipe for bread rolls.
She uses 400 g of flour.
How much of each of the other ingredients does she use?
Recipe: Makes 15 bread rolls
500 g flour
10 g salt
8 g yeast
30 mL oil
350 mL water
Answers
Answer:
Salt = 8 g
Yeast = 6.4 g
Oil =24 ml
Water = 280ml
Step-by-step explanation:
[tex]Salt = \frac{10}{500}*400 = 2*4 = 8[/tex]
[tex]yeast =\frac{8}{500}*400= \frac{32}{5}=6.4[/tex]
[tex]Oil =\frac{30}{500}*400=6*4=24 ml[/tex]
[tex]Water = \frac{350}{500}*400=70*4=280 ml[/tex]

If ∠R and ∠S are supplementary angles and m∠R = 39°, find m∠S.
Answers
Answer: m∠S=141°
Step-by-step explanation:
Here, we need to know the definition of supplementary angles. Supplementary angles are two angles that add up to 180°. If you need a more detailed graphical explanation, please refer to the attachment below.
---------------------------------------------------------------------------------------------
Given
m∠R=39°
Solve
Given
m∠R + m∠S=180
Substitute value
39 + m∠S=180
Subtract 39 on both sides
39 + m∠S - 39=180 - 39
m∠S=141

Suppose that the number of bacteria in a certain population increases according to a continuous exponential growth model. A sample of 1500 bacteria selected
from this population reached the size of 1805 bacteria in four hours. Find the hourly growth rate parameter.
Note: This is a continuous exponential growth model.
Write your answer as a percentage. Do not round any intermediate computations, and round your percentage to the nearest hundredth.

Answers
Answer:
The hourly growth rate parameter is of 4.74%
Step-by-step explanation:
Continuous growth model:
The continuous growth model for a population after t hours is given by:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(0) is the initial population and r is the hourly growth rate parameter, as a decimal.
A sample of 1500 bacteria selected from this population reached the size of 1805 bacteria in four hours.
This means that [tex]P(0) = 1500, P(t) = 1805, t = 4[/tex]
Find the hourly growth rate parameter.
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]1805 = 1500(1+r)^4[/tex]
[tex](1+r)^4 = \frac{1805}{1500}[/tex]
[tex]\sqrt[4]{(1+r)^4} = \sqrt[4]{\frac{1805}{1500}}[/tex]
[tex]1 + r = (\frac{1805}{1500})^{\frac{1}{4}}[/tex]
[tex]1 + r = 1.0474[/tex]
[tex]r = 0.0474[/tex]
0.0474*100% = 4.74%
The hourly growth rate parameter is of 4.74%
Solve the simultaneous equations
2x - 5y = 9
3x + 4y = 2
Answers
Answer:
(2, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 5y = 9 → (1)
3x + 4y = 2 → (2)
Multiplying (1) by 4 and (2) by 5 and adding the result will eliminate the y- term
8x - 20y = 36 → (3)
15x + 20y = 10 → (4)
Add (3) and (4) term by term to eliminate y
23x + 0 = 46
23x = 46 ( divide both sides by 23 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (2)
3(2) + 4y = 2
6 + 4y = 2 ( subtract 6 from both sides )
4y = - 4 ( divide both sides by 4 )
y = - 1
solution is (2, - 1 )
An entrepreneur is considering the purchase of a coin-operated laundry.

If you were to test the null hypothesis that the daily mean revenue was $675, which test would you use
Answers
Answer:
One sample t test
Step-by-step explanation:
A one proportion sample t test is employed when we intend to test the sample mean of a certain sample against a particular or specified population property . In the scenario above, we could use the information given to obtain the one sample proportion test statistic by using the formular :
Test statistic = (xbar - μ) ÷ (σ/sqrt(n))
Where, xbar = sample mean ;
μ = population mean
σ = population standard deviation
n = sample size
Using the test statistic, we can then obtain the Pvalue and compare to the specified α - level

Answers
Answer:
P(t) = 3000 * 4^(t/10)
Step-by-step explanation:
There is more than one way to get an exponential function out of the information given. The way the question is worded, however, seems to suggest the following type of answer:
One general form of the exponential function is y = a·bx, where a is the initial value, and b is the growth or decay factor. So right away we can say that a = 2300.
Now for the growth factor. When something is increasing or decreasing by a certain percentage, we are adding or subtracting that percentage to the 100% (which is equal to 1) that exists currently. So here we're increasing by 11%, or 0.11. Then the growth factor b is (1 + 0.11), or 1.11.

3 2/6+8 2/9-1 1/2 ?????????
Answers
Answer:
10 1/18
Step-by-step explanation:
3 2/6 + 8 2/9 - 1 1/2 = ?
First, we need to find the common denominator, which I will choose to be 18, which means I will need to convert all the fractions.
3 6/18 + 8 4/18 - 1 9/18 = ?
Now, we solve.
3 6/18 + 8 4/18 - 1 9/18 = 10 1/18

Step-by-step explanation:
Given that :The radius of a circle is 10 m.to find :Find the circumference to the nearest tenth.formulas used :circumference = 2 × π × rwhere,π = 22/7
r = 10 m
explanation :⟼ c = 2πr
⟼ c = 2 × 22/7 × 10 m
⟼ c = 2 × 3•14 × 10m
⟼ c = 6•28 × 10 m
⟼ c = 62•8 m
Round to the nearest tenth :⟼ c = 62•8 m
⟼ c = 60 m
∴ circle circumference is 60 m.
