Answer:
AD = 3
Step-by-step explanation:
Pythagoras theorem formula: a² + b² = c² (c being the hypotenuse, the longest side of the triangle).
Using this formula, you can easily say that c²-b²=a². c=5, b=4, making the equation 5² - 4² = a ².
Expanding the formula, you'll get 25 - 16 = a².
25 - 16 = 9.
This means that 9 = a².
To find a, you need to root 9. Using a calculator, you'll know that this number is 3, meaning that AD = 3.

For the first problem, you can convert [tex]-1 \frac{7}{10}[/tex] as a decimal, which is [tex]-1.7[/tex]. I've attached an image below and the red dot should be correct plotted version.
For the second problem, you can say something like Remy should look at the mixed fraction separate when plotting a mixed fraction. That way, it'll be easier to plot.

Answer:
a(6) = 2 [tex]\sqrt{3}[/tex] , b(10) = 15 [tex]\sqrt{2}[/tex]
Step-by-step explanation:
A. a(x) = [tex]\sqrt{2x}[/tex]
a(6) = [tex]\sqrt{2(6)}[/tex]
a(6) = [tex]\sqrt{12}[/tex]
a(6) = [tex]\sqrt{4}\sqrt{3}[/tex]
a(6) = 2 [tex]\sqrt{3}[/tex]
B. b(x) = 3 [tex]\sqrt{5x}[/tex]
b(10) = 3 [tex]\sqrt{5(10)}[/tex]
b(10) = 3 [tex]\sqrt{50}[/tex]
b(10) = 3 [tex]\sqrt{25}[/tex] [tex]\sqrt{2}[/tex]
b(10) = 3 x 5 [tex]\sqrt{2}[/tex]

A runner can run 5 miles in 26 minutes at this rate how many miles can he run and 41.6 minutes?
Answer:
8 miles
Step-by-step explanation:
Given: A runner can run 5 miles in 26 minutes, 41.6 minutes = ___
To find: At this rate, how many miles can he run and 41.6 minutes?
Solution: If the runner ran 5 miles in 26 minutes, to find how far he ran in 41.6 minutes, set up a fraction:
let x be the variable
[tex]\frac{26}{5} = \frac{41.6}{x}[/tex]
Apply fraction cross multiply;
[tex]26x=5\cdot \:41.6[/tex]
[tex]26x = 208[/tex]
Divide both sides by 26
[tex]\frac{26x}{26}=\frac{208}{26}[/tex]
Simplify
[tex]x = 8[/tex]
Then, at the rate, the runner ran 8 miles 41.6 minutes

When Nathaniel left his house in the morning, his cell phone battery was partially
charged. The charge remaining in Nathaniel's battery, as a percentage, can be
modeled by the equation B = 52 - 6.5t, where t is the number of hours since
Nathaniel left his house. What is the slope of the equation and what is its
interpretation in the context of the problem?
Answer:
Slope -6,5
Step-by-step explanation:
Slope of the equation is -6.5 which is mean that every our his battery lose 6.5 percent of charge. 52 represent here the percentage of battery at the time he left the house.

A box contains 3 defective batteries and 7 good ones. You reach in and pull out three
batteries. What is the expected number of defective batteries?
Answer:
The expected number of defective batteries to be pulled out is 0.9, which rounded to the nearest integer gives a total of 1, that is, 1 of the 3 batteries is expected to be defective.
Step-by-step explanation:
Given that a box contains 3 defective batteries and 7 good ones, and I reach in and pull out three batteries, to determine what is the expected number of defective batteries, the following calculation must be performed:
3 + 7 = 100
3 = X
10 = 100
3 = X
3 x 100/10 = X
300/10 = X
30 = X
3 x 3/10 = X
0.9 = X
Therefore, the expected number of defective batteries to be pulled out is 0.9, which rounded to the nearest integer gives a total of 1, that is, 1 of the 3 batteries is expected to be defective.

An article reports on an experiment in which each of five groups consisting of six rats was put on a diet with a different carbohydrate. At the conclusion of the experiment, the DNA content of the liver of each rat was determined (mg/g liver), with the following results:
Carbohydrate xi.
Starch 2.58
Sucrose 2.63
Fructose 2.13
Glucose 2.41
Maltose 2.49
Assuming also that Σ Σ xij^2 = 185.4, does the data indicate that true average DNA content is affected by the type of carbohydrate in the diet? Construct an ANOVA table and use a 0.05 level of significance.
Answer:
H0 is rejected, Hence the true average DNA content is affected by the type of carbohydrate in the diet between samples

Answer:
D. -9p + 0.5
Step-by-step explanation:
2(-4p-1) + (2.5-p)
Distribute the 2 and invisible 1
so
-8p - 2 + 2.5 - p
Combine like terms
-8 p + (-p) = -9p
-2+2.5 = 0.5
so

how many times does 48 go into 123
Answer:
48 goes into 123 about 2.5625 times.
Step-by-step explanation:
To determine how many times does 48 go into 123, the following mathematical calculation must be performed, by which 123 will be divided by 48 to obtain said number of times:
123/48 = X
2.5625 = X
Therefore, 48 goes into 123 about 2.5625 times.
