Answer:
7500 kg
Step-by-step explanation:
t = tonnes
[tex] \because \: 1 \: t = 1000 \: kg \\ \therefore \: 7.5 \: t = 7.5 \times 1000 = 7500 \: kg[/tex]
Answer:
7.5 tonnes = 7500 kg
Step-by-step explanation:
7.5 t
Here t is tonnes
So changing tonnes into kg, we multiply by 1000
= 7.5 * 1000 kg
= 7500 kg

Determine the equation of the inverse of y = 7x + 2
Answer:
x=7y+2
Step-by-step explanation:
switch the letters
Answer: y=(x-2)/7
Step-by-step explanation:
To find the inverse of the equation, you want to replace all the x with y and all the y with x. Our equation would be:
x=7y+2
Now that we have our equation, we can solve for y.
x-2=7y
y=(x-2)/7

Which pair of expressions is equivalent using the Associative Property of Multiplication?
A6(4a ⋅ 2) = 24a ⋅ 12
B 6(4a ⋅ 2) = (4a ⋅ 2) ⋅ 6
C6(4a ⋅ 2) = 6 ⋅ 4a ⋅ 2
D6(4a ⋅ 2) = (6 ⋅ 4a) ⋅ 2
Answer:
Step-by-step explanation:
In the associative property of multiplication, the product of the multiplication of 3 or more numbers is the same irrespective of how they are grouped. This means that irrespective of the bracket or which number comes first, the product will always be the same.
From the given scenarios, the pair of expressions that are equivalent using the Associative Property of Multiplication are
B 6(4a ⋅ 2) = (4a ⋅ 2) ⋅ 6
C 6(4a ⋅ 2) = 6 ⋅ 4a ⋅ 2
D6(4a ⋅ 2) = (6 ⋅ 4a) ⋅ 2
The results are the same irrespective of the arrangement of the numbers.

Does the table represent a function? why or why not? HELP WANTEDD
Answer:
C no, because one x value corresponds to two different y values
Step-by-step explanation:
The x value of 3 goes to two different y values
This means this cannot be a function
This is not a one to one correspondence
Answer: C
Step-by-step explanation: In order for a table to represent a function each x-value needs to correspond to exactly 1 y-value.
Notice that in the table, the 3 appears twice and it corresponds to a 5 in one case and it corresponds to a 6 in another case.
Since the x-value of 3 corresponds to more than 1 y-value,
no, this table does not represent a function.

Use the equation Y = {/27x-54 +5.
Which is an equivalent equation of the form
y=avx-h+k
y=-273x + 2+5
y=-3x+2 +5
y=34x-2 +5
y=273/x-2 +5
Answer:
y= 34x- 2 +5 (C)
Step-by-step explanation:
The equation: y = 27x-54 +5
We are to determine an equivalent equation of the form y=avx -h+k from the options given.
From the above, av = two digit coefficient of x. Hence av is constant.
h and k are also constant.
Let's check out the option to find the equation that is in the form y=avx-h+k
a) y=-273x + 2+5
In this equation, the coefficient of x is a 3-digit number. The option is wrong.
b) y=-3x+2 +5
In this equation, the coefficient of x is a 1-digit number. The option is wrong.
c) y=34x -2 +5
In this equation, the coefficient of x is a 2-digit number.
av = 34, h= 2 and k = 5
This equation is in the form of y=avx -h+k
The option is correct.
d) y=273/x-2 +5
This equation is not in the form of y=avx -h+k
The option is wrong.

Problem 10.084 An article in Knee Surgery, Sports Traumatology, Arthroscopy (2005, Vol. 13, pp. 273-279), considered arthroscopic meniscal repair with an absorbable screw. Results showed that for tears greater than 25 millimeters, 14 of 17 repairs were successful while for shorter tears, 22 of 31 repairs were successful. (a) Is there evidence that the success rate is greater for longer tears? Use alpha equals 0.05 . What is the Upper P -value?
Answer:
The p-value = 0.181186
The p-value is greater than the significance level at which the test was performed, hence, we fail to reject the null hypothesis & say that there isn't enough evidence to suggest that the success rate of repair of longer tears is greater than the success rate of repair of shorter tears.
Step-by-step explanation:
This is a two-sample hypothesis test as we want to test the whether the success rate for one group of tears is more than the other
For hypothesis testing, the first thing to define is the null and alternative hypothesis.
In hypothesis testing, especially one comparing two sets of data, the null hypothesis plays the devil's advocate and usually takes the form of the opposite of the theory to be tested. It usually contains the signs =, ≤ and ≥ depending on the directions of the test. It usually maintains that, with random chance responsible for the outcome or results of any experimental study/hypothesis testing, its statement is true.
The alternative hypothesis usually confirms the theory being tested by the experimental setup. It usually contains the signs ≠, < and > depending on the directions of the test. It usually maintains that significant factors other than random chance, affect the outcome or results of the experimental study/hypothesis testing and result in its own statement.
For this question where we are testing if the success rate of longer tears is greater than the success rate of shorter tears,
The null hypothesis is that there is no significant difference in the success rate for the two types of tears. That is, there isn't enough evidence to suggest that the success rate of longer tears is greater than the success rate of shorter tears.
The alternative hypothesis is that there is enough evidence to suggest that the success rate of longer tears is greater than the success rate of shorter tears.
Mathematically, if the success rate of longer tears is p₁, success rate of repair of shorter tears is p₂. And the difference between the two success rates is μ = p₁ - p₂,
The null hypothesis is represented as
H₀: μ = 0 or p₁ = p₂
The alternative hypothesis is represented as
Hₐ: μ > 0 or p₁ > p₂
We then calculate the test statistic
The test statistic for two samples test is given as
t = (p₁ - p₂)/σ
σ = √{[p₁(1-p₁)/n₁] + [p₂(1-p₂)/n₂]}
p₁ = success rate of repair of longer tears = (14/17) = 0.8235
n₁ = 17
p₂ = success rate of repair of shorter tears = (22/31) = 0.7097
n₂ = 31
σ =
√{[0.8235(1-0.8235)/17] + [0.7097(1-0.7097)/31]}
σ = √[(0.8235×0.1765/17) + (0.7097×0.2903/31)]
= √(0.0085498676 + 0.0066459971)
= √0.0151958647 = 0.1232715081 = 0.1233
t = (p₁ - p₂)/σ
t = (0.8235 - 0.7097)/0.1233
t = 0.92
checking the tables for the p-value of this t-statistic
Degree of freedom = df = n₁ + n₂ - 2 = 17 + 31 - 2 = 46
Significance level = 0.05
The hypothesis test uses a one-tailed condition because we're testing only in one direction.
p-value (for t = 0.92, at 0.05 significance level, df = 46, with a one tailed condition) = 0.181186
The interpretation of p-values is that
When the (p-value > significance level), we fail to reject the null hypothesis and when the (p-value < significance level), we reject the null hypothesis and accept the alternative hypothesis.
So, for this question, significance level = 0.05
p-value = 0.181186
0.181186 > 0.05
Hence,
p-value > significance level
This means that we fail to reject the null hypothesis & say that there isn't enough evidence to suggest that the success rate of repair of longer tears is greater than the success rate of repair of shorter tears.
Hope this Helps!!!

If the first step in the solution of the equation -8 - 7x = -5x - 10 is "add 10," then what should the next step be?
add 7x
add 8
add 5x
Answer:
The answer is add 7x.
Step-by-step explanation:
When the first step is to add 10 to both sides :
[tex] - 8 - 7x = - 5x - 10[/tex]
[tex] - 8 - 7x + 10 = - 5x - 10 + 10[/tex]
[tex] - 7x + 2 = - 5x[/tex]
Next, you have to add 7x to both sides to eliminate -7x on the left side :
[tex] - 7x + 2 = - 5x[/tex]
[tex] - 7x + 2 + 7x = - 5x + 7x[/tex]
[tex]2 = 2x[/tex]
Answer:
add 7x
Step-by-step explanation:
This would be the answer because if you have already added 10 to the right side of the equation and have erased the constant, you would then need to erase the variable on the other side to make it equal. The variable on the other side is 7x, which gives you the answer.

Answer:
x = 65°
Step-by-step explanation:
Find the measure of the other two angles using the Supplementary Angles theorem:
180 - 105 = 75°
180 - 140 = 40°
The sum of all of the angles in a triangle is equal to 180°, therefore:
180 = 75 + 40 + x
180 = 115 + x
65 = x
x = 65°
