Answer:
9-3=6
Step-by-step explanation:
An addition/subtraction fact family has 2 addition equations and 2 subtraction ones.
The question already states both addition ones, but only one subtraction
The subtraction one stated is 9-6=3
The opposite is 9-3=6

Step-by-step explanation:
10.00000000000000000 is the same as just 10
so through bodmas/bidmas you know thta the multiplication ha sto be done first so 8 x 10 =80
no add the first value.
12+80=92
9. The maximum value of a data set
consisting of 25 positive integers is 84. A
new data set consisting of 26 positive
integers is created by including 96 in the
original data set. Which of the following
measures must be 12 greater for the new
data set than for the original data set?
Answer:
Let m be the minimum value of original data set.
Given -
The range of original data set = 84 -mA new data set consists of 26 positive integers and 96 original data set.Therefore, the range of new data set is 96-m.
Now, we can find the difference between two ranges by subtracting the ranges -
[tex] \\ \implies \sf \: (96 - m) - (84 - m) \\ \\ \\ \sf \footnotesize \: using \: \: distributive \: \: property \: - \\ \\ \\ \bf \: it \: \: will \: \: be \: \: equal \: \: to \: \: 12. \\ [/tex]
Therefore, the range of the new data set must be greater than the range of original data set.

Step-by-step explanation:
A car rental business charges a daily fee along with a one-time fixed charge to refuel the car when it is returned. The equation the business uses to calculate the total rental cost, c is c=15d+24c = 15 d + 24, where d represents the number of rental days. What is the daily increase in the total cost of the rental?
Answer:
$15
Step-by-step explanation:
Since we are given the actual equation, which is c = 15d + 24 (it is repeated in the question twice) we can see that the independent variable would be the number of days that the car is rented. Therefore we can simply plug in a value for this to calculate c. So below we can see the total cost for 1 day rent (d = 1 ) and 2 days rented (d = 2)
c = 15(1) + 24 = 39
c = 15(2) + 24 = 54
Now we can simply subtract these two values and to see the daily increase
54-39 = 15
Therefore we can see that the total price will increase by $15 for each day that it is rented.

A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for type I ovens is greater than the repair cost for type II ovens. A sample of 61 type I ovens has a mean repair cost of $79.60, with a standard deviation of $23.47. A sample of 45 type II ovens has a mean repair cost of $75.25, with a standard deviation of $15.07. Conduct a hypothesis test of the technician's claim at the 0.05 level of significance. Let μ1 be the true mean repair cost for type I ovens and μ2 be the true mean repair cost for type II ovens.Step 3 of 4 : Determine the decision rule for rejecting the null hypothesis H0.

The question is missing some parts. Here is the complete question.
A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for type I ovens is greater than the repair cost in type II ovens. A samplle of 61 type I ovens has a mean repair cost of $79.60, with a standard deviation of $23.47. A sample of 45 type II ovens has a mean repair cost of $75.25, with standar deviation of $15.07. Conduct a hypothesis test of the technician's claim at the 0.05 level of significance. Let [tex]\mu_{1}[/tex] be the true mean repair cost for type I ovens and [tex]\mu_{2}[/tex] be the true mean repair cost for type II ovens.
Step 1 of 4: State null and alternative hypothesis for the test.
Step 2 of 4: Compute the value of test statistics. Round your answer to 2 decimal places.
Step 3 of 4: Determine the decision rule for rejecting the null hypothesis. Round the numerical portion of your answer to 3 decimal places.
Step 4 of 4: Make the decision for the hypothesis test. (Reject or fail to reject Null Hypothesis)
Answer and Step-by-step explanation:
First, state null and alternative hypothesis:
[tex]H_{0}: \mu_{1}=\mu_{2}[/tex]
[tex]H_{a}: \mu_{1}>\mu_{2}[/tex]
Use z-statistics:
[tex]z = \frac{x_{1}-x_{2}}{y}[/tex]
where x₁ and x₂ are the means and:
[tex]y=\sqrt{\frac{s_{1}^{2}}{n_{1}}+\frac{s_{2}^{2}}{n_{2}} }[/tex]
Calculating value of test stattistic:
[tex]y=\sqrt{\frac{(23.47)^{2}}{61}+\frac{75.25^{2}}{45} }[/tex]
[tex]y = \sqrt{9.030+5.046}[/tex]
[tex]y = \sqrt{14.076}[/tex]
y = 3.752
[tex]z = \frac{79.6-75.25}{3.752}[/tex]
z = 1.16
The test statistics is z = 1.16
The decision rule for rejecting null hypothesis is: [tex]\alpha[/tex] ≤ test statistics
Using z-score table, it is possible to determine p-value, which is:
p-value = 0.877
Comparing p-value with level of significance (α = 0.05):
0.877 > 0.05
Therefore, we fail to reject the null hypothesis.

-3/2+3/7 The denominator needs to be the same
Answer:
Step-by-step explanation:
To make the denominator same, find Lease common denominator of 2 and 7
LCD of 2 and 7 = 2*7 = 14
[tex]\frac{-3}{2}+\frac{3}{7}=\frac{-3*7}{2*7}+\frac{3*2}{7*2}\\\\\\=\frac{-21}{14}+\frac{6}{14}\\\\\\=\frac{-21+6}{14}\\\\\\=\frac{-15}{14}\\\\\\=-1\frac{1}{14}[/tex]
Answer:
-15/14
Step-by-step explanation:
Find the Least Common Denominator (LCD) for the two fractions, so the operation can be performed. The LCD is constructed from the factors the fractions have, making sure that all factors they need are included.
In our case, for the first fraction, the factor 2 is needed, and for the second fraction, the factor 7 is needed. Then the LCD is: 2 * 7 = 14
So now, let's write both denominators with the same LCD, by finding the appropriate equivalent fractions:
- 3 /2 = - (3*7) / (2*7) = -21 / 14
3 / 7 = (3*2) / (7*2) = 6 / 14
Therefore the combining can now be performed and renders:
- (21/ 14) + (6/ 14) = - (15/14)
The result is then the fraction : -15/14
Graph the image of the given triangle under a dilation with a scale factor of –4 and center of dilation (0,0).
Step-by-step explanation:
Hey there!
The coordinates of a triangle are;
A (1,2)B (1,-2)C (-2,-2)Scale factor = -4 and centre at (0,0)Now, We have;
P(x,y)----------- P'(kx, ky)
Keep formula;
A(1,2)---------- A'(-4×1 ,-4×2)
= A'(-4, -8)
B(1,-2)------------- B'(-4,8)
C(-2,-2)-------------C'(8,8)
[ The A' should be kept in (-4,-8). There was no place in this graph so, i kept it just below -7. Please while plotting remember to keep it on "-8".]

If QR = 18, RS = x -11, and QS = 2x - 11, what is QS?
Answer:
QS =25
Step-by-step explanation:
QR + RS = QS
18 + (x-11) =2x-11
7 +x =2x -11
18=x
Plug in x
2(18) -11
36-11
QS=25
18 + (18-11) = 2(18)- 11
18+ 7 = 36 -11
25= 25
True

Which number is a counterexample to the following statement? All numbers that are divisible by 2 are divisible by 4.
A. 0
B. 12
C. 28
D. 42
Using divisibility concepts, a counterexample to the statement is given by option the number 42, option D.
-------------
If the remainder of the division of A by B is 0, it is said that A is divisible by B.-------------
In option A, 0 is divisible by both 2(0/2 = 0) and 4(0/4 = 0), so it is not a counterexample.In option B, 12 is divisible by both 2(12/2 = 6) and 4(12/4 = 3), so it is not a counterexample.In option C, 28 is divisible both by 2(28/2 = 14) and 4(14/2 = 7), so it is not a counterexample.In option D, 42 divided by 4 is 10 with a remainder of 2, thus 42 is not divisible by 4, being a counterexample to the statement.A similar problem is given at https://brainly.com/question/24354438
