Old machine: 8.2, 8.0, 7.9, 7.9, 8.5, 7.9, 8.1,8.1, 8.2, 7.9
New machine: 8.0, 8.1, 8.0, 8.1, 7.9, 8.0, 7.9, 8.0, 8.1
Use a 0.05 significance level to test the claim that the volumes of Bubbly Beverage filled by the old machine vary more than the volumes of juice filled by the new machine.
Answer:
We Reject the Null, H0 and conclude that the volume of juice filled by old machine varies more than volume filled by new machine
Step-by-step explanation:
Given the data:
Old machine: 8.2, 8.0, 7.9, 7.9, 8.5, 7.9, 8.1,8.1, 8.2, 7.9
Sample size, n = 10
Using calculator :
s1² = 0.37889.
New machine: 8.0, 8.1, 8.0, 8.1, 7.9, 8.0, 7.9, 8.0, 8.1
Sample size, n = 9
s2² = 0.006111
Hypothesis :
H0 : s1² = s2²
H1 : s1² > s2²
New machine :
s2² = 0.006111 ; n = 9
Using the Ftest :
Ftest statistic = larger sample variance / smaller sample variance
Ftest statistic = 0.37889 / 0.006111
Ftest statistic = 62.0
Decision region :
Reject H0 ; If Test statistic > Critical value
The FCritical value at 0.05
DFnumerator = 10 - 1 = 9
DFdenominator = 9 - 1 = 8
Fcritical(0.05, 9, 8) = 3.388
Since 62 > 3.388 ; Reject H0 and conclude that volume filled by old machine varies more than volume filled by new machine

solve for x please help!
Answer:
x = -1/4
Step-by-step explanation:
-4(-5x-3) = 7
Distribute
20x +12 = 7
Subtract 12 from each side
20x+12-12 = 7-12
20x = -5
Divide by 20
20x/20 = -5/20
x = -1/4

Maggie's brother is 6 years younger than four times her age. The sum of their ages is
59.
How old is Maggie?
Maggie is
years old.
Answer:
Maggie is 11 years old
Step-by-step explanation:
let m be Maggie and b be her brother.
[tex]m+b=59[/tex]
[tex]b=4m-6[/tex]
substitute for b.
[tex]m+4m-6=59[/tex]
[tex]5m-6=59[/tex]
add 6 to both sides
[tex]5m=55[/tex]
divide by 5 on both sides
[tex]m=11[/tex]
double check by finding the brother's age by substituting for m
[tex]11+b=59[/tex]
[tex]b=48[/tex]
Find mABC.
A. 102°
B. 54°
C. 14°
D. 78°
By the supplementary angles theorem, we know that both of the angles add up to equal 180°, so:
(4x + 22) + (8x - 10) = 180
12x + 12 = 180
12x = 168
x = 14
Now you just have to plug in x into the value for ∠ABC:
∠ABC = 4x + 22
∠ABC = 4(14) + 22
∠ABC = 46 + 22
∠ABC = 68°
Answer:
D = 78
Step-by-step explanation:
The two angles form a straight line so they add to 180
4x+22 + 8x-10 = 180
Combine like terms
12x +12 =180
Subtract 12 from each side
12x+12-12 = 180-12
12x = 168
Divide by 12
12x/12 =168/12
x=14
We want to find ABC
4x+22 = 4*14+22 = 56+22 = 78

You have $90,000 in cash. You can deposit it today in a mutual fund earning 7.5
percent semiannually; or you can wait, enjoy some of it, and invest $12,000 in your
brother's business after two years. Your brother is promising you a return of at least 12
percent on your investment. Whichever alternative you choose, you will need to cash
in at the end of 8 years. Assume your brother is trustworthy and that both investments

The acute angle of the right angle triangle are in the ratio of 4:5
Answer:
Since the triangle is a right angled triangle, one of the angles is 90°. In the right angled triangle, the acute angles are in the ratio 4:5. Let the measures of the acute angles of the triangle in degrees be 4k and 5k, where k is a constant.
Step-by-step explanation:
hope it helps.
Answer:
40and50
Step-by-step explanation:
let the acute angles be 4x and 5x then,
4x+5x+90=180 [sum of all angles of a right angled triangle]
or,9x=180-90
or,x=90/9
x=10
4x=4×10=40
5x=5×10=50
Please help me. I don't understand fractions here is my problem.
Add:
5/24+9/20
Answer:
79/120
Step-by-step explanation:
5/24+9/20
to add the fractions the denominator (bottom part) has to be the same. ex you can add one third and one third to make two thirds. but you wont know what 1/2 + 1/3 is.
convert to same denominator. to do this, the fractions themselves need to stay the same value but the bottom number needs to change. ex 1/2=2/4 and 1/3= 2/6. when you multiply and divide the top and bottom part of the fraction by the same number, the value of the fraction stays the same. ex 3/6 divide both parts by 3 you get 1/3. so 3/6=1/3
to get the common denominator we have to find the least common multiple, or LCM (since 5 and 9 dont share any common factors.)
24 and 20 LCM
=120
convert both 5/24+9/20 to x/120 and y/120
5/24 multiply by 5 on top and bottom
=25/120
9/20 multiply by 6 on top and bottom
=54/120
25/120+54/120
=(25+54)/120
=79/120
2. Mandla spent one quarter of his pocket money on sweets. a. What fraction does he have left? b. If he had R40 pocket money, how much did he spend?
Answer:
a. 3/4 of pocket money left
b. R10
Step-by-step explanation:
a. 4/4 - 1/4 = 3/4
b. 40/4 = 10 = 1/4 of pocket money
(a). The fraction of pocket money left is 3/4
(b). If he had R40 pocket money, he spend R10.
What is the Ratio?The ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
Mandla spent one-quarter of his pocket money on sweets
Let x be the total amount of pocket money Mandla had originally
Solution of (a).
⇒ x - (1/4)x
⇒ (3/4)x
The fraction of pocket money left = 3/4
Solution of (b).
1/4 of pocket money
⇒ (1/4)x
⇒ (1/4)40
⇒ 10

Answer:
U = 67.6 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos U = adj side / hypotenuse
cos U = sqrt(10)/ sqrt(69)
cos U = sqrt(10/69)
Taking the inverse cos of each side
cos ^-1( cos U) = cos ^-1(sqrt(10/69))
U = 67.62335
To the nearest tenth
U = 67.6 degrees
