Answer:
F.) H0:μ=4.55, Ha:μ≠4.55
A.) H0:μ=115, Ha:μ<115
H0:μ=69 , Ha:μ>69
Step-by-step explanation:
The null and alternative hypothesis are used in hypothesis testing.
Generally, both hypothesis negatives each other, with the alternative being the opposite of the null hypothesis.
1)the mean value of the population is 4.55 ; the researcher aims to test if the mean value differs from thus value, hence, Alternative ; μ ≠ 4.55
2.) The mean resting heart rate is said to be 115 ; this is the null claim. The reaesrch aims to test if heart rate slows down with age. Hence, the alternative will be to show that mean rate lesser Than 115 as claimed (μ < 115)
3.) Theean height of the population is claimed to be 69. Researcher aims to test if some people within the population have mean height abive this said height. (μ > 69)
Suppose that two fair dice are rolled. Find the probability that the number on the first die is a 6 or the number on the second die is a 4.
Answer:
[tex]Probability = \frac{1}{36}[/tex]
Step-by-step explanation:
Given
Two fair dice
Required
Determine the probability that the outcomes is 6 on the first and 4 on the second
First, we need to write out the sample space of both:
[tex]S_1 = \{1,2,3,4,5,6\}[/tex]
[tex]n(S_1) = 6[/tex]
[tex]S_2 = \{1,2,3,4,5,6\}[/tex]
[tex]n(S_2) = 6[/tex]
Where S1 represents the first and S2, the second
The probability of outcome of 6 on the first is:
[tex]P(6) = \frac{n(6)}{n(S_1)}[/tex]
[tex]P(6) = \frac{1}{6}[/tex]
The probability of outcome of 4 on the second is:
[tex]P(4) = \frac{n(4)}{n(S_2)}[/tex]
[tex]P(4) = \frac{1}{6}[/tex]
So, the required probability is then calculated as:
[tex]Probability = P(6) * P(4)[/tex]
[tex]Probability = \frac{1}{6} *\frac{1}{6}[/tex]
[tex]Probability = \frac{1}{36}[/tex]

What is the value of x
Answer:
x = 20
Step-by-step explanation:
Exterior angle theorem
Exterior angle = Interior opposite angle 1 + Interior opposite angle 2
(9x + 16)° = 90 + (5x - 14)°
9x + 16 = 90 + 5x - 14
9x - 5x = 90 - 14 - 16
4x = 90 - 30
4x/4 = 60/4
x = 20

Answer:
(-4,-1)
Step-by-step explanation:
Determine the equation of the perpendicular bisector JK whose endpoints are J(-4,9) and K(6,1). Show all your work below. (Use of the grid is optional.)
Answer:
[tex]y=\frac{5}{4}x+\frac{15}{4}[/tex]
Step-by-step explanation:
Coordinates of segment with endpoints J and K are,
J(-4, 9) and K(6, 1)
Midpoint of the segment JK = [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
= [tex](\frac{-4+6}{2},\frac{9+1}{2})[/tex]
= (1, 5)
Slope of JK, [tex](m_1)=\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{9-1}{-4-6}[/tex]
= [tex]-\frac{4}{5}[/tex]
Let the equation of perpendicular bisector passing through [tex](x_1,y_1)[/tex] and slope [tex]m_2[/tex] is,
[tex]y-y_1=m_2(x - x_1)[/tex]
By the property of perpendicular lines,
[tex]m_1\times m_2=-1[/tex]
[tex]-\frac{4}{5}\times m_2=-1[/tex]
[tex]m_2=\frac{5}{4}[/tex]
Therefore, equation of the line passing through midpoint (1, 5) and slope = [tex]\frac{5}{4}[/tex] will be,
[tex]y-5=\frac{5}{4}(x-1)[/tex]
[tex]y=\frac{5}{4}x-\frac{5}{4}+5[/tex]
[tex]y=\frac{5}{4}x+\frac{15}{4}[/tex]
If someone can please do the check for me, please.
Whats the question theres nothing attached
34.00 -A video game is on sale at Amazon for 35% off the original price of $28.50. Both Pat and Henri want to purchase the game, but they only have $21 each. They will have to pay 10% sales tax. Pat and Henri have different strategies to calculate the price and decide if they have enough money to get the game. Pat takes 35% of $28.50 and subtracts that from the original price. She takes 10% of the sale price and adds it to the sale price to find the total amount she would have to pay. Henri finds 65% of the original price and then calculates 110% of the sale price. What is the sale price of the video game with tax? (1 point) Will Pat's strategy calculate the correct total? Explain the calculations. (2 points) Will Henri's strategy calculate the correct total? Explain the calculations. (2 points) Do they each have enough to purchase the game? (2 points) Explain your answers using complete sentences and show your work
Answer:
Sale price of video game with tax = $20.3775
Yes, they both have enough money to purchase the video game.
Step-by-step explanation:
Given that:
Original price of video game = $28.50
Discount on original price = 35%
Sales tax = 10%
Money available with Pat and Henri = $21 each
First of all, let us find out the price as per Pat's method.
Step 1:
Taking 35% of $28.50
[tex]\Rightarrow \dfrac{35}{100}\times \$28.50 = \$9.975[/tex]
Step 2:
Subtract from $28.50 to find the sale price:
$28.50 - $9.975 = $18.525
Step 3:
Take 10% of sale price:
[tex]\$18.525\times \dfrac{10}{100} = \$1.8525[/tex]
Step 4:
Add to sale price to get the final amount to be paid:
$18.525 + $1.8525 = $20.3775
Now, let us use Henri's method:
Step 1:
Find 65% of original price:
[tex]\dfrac{65}{100}\times $28.50 = \$18.525[/tex]
Step 2:
Find 110%:
[tex]\dfrac{110}{100}\times \$18.525 = \bold{\$20.3775}[/tex]
Sale price of video game with tax = $20.3775
Yes, they both have enough money to purchase the video game.

Maddelein deposited $750 into an investment account that earns 1.5% daily compounded interest after year how much money will be in the account
1285.37
You can use the formula for compound interest:
P(1+R)^t
P = the principle, the amount of money
(1+R) = the rate, (%) as a decimal plus 1
^t = to the power of the number of years
Substitute the values:
750(1+0.08)^7
750(1.08)^7
1285.37

John is x years old, Ahmad is 3 years older than John. The total of their age is 63 years. Form and equation and work out the age of Ahmad.
Answer:
x = john
x + 3 = ahmad
x + (x + 3) = 63
2x + 3 = 63
2x = 60
x = 30
john is 30 so ahmad is 33

Use root test to determine the following series is convergent/divergent or inconclusive
By the root test, the series converges. We have
[tex]\displaystyle\lim_{k\to\infty}\sqrt[k]{\left|(-1)^k\frac{k^3}{3^k}\right|}=\lim_{k\to\infty}\frac{\sqrt[k]{k^3}}3=\frac13\lim_{k\to\infty}k^{\frac3k}=\frac13[/tex]
which is less than 1.
In case it's not clear why [tex]k^{3/k}[/tex] should converge to 1:
[tex]\displaystyle\lim_{k\to\infty}k^{\frac3k}=\lim_{k\to\infty}\exp\left(\ln k^{\frac3k}\right)=\exp\left(\lim_{k\to\infty}\frac{3\ln k}k\right)\to e^0=1[/tex]
