-6 X 7
I will pay you back if you answer this correctly.
Answer:
-6 time 7 = -42
Step-by-step explanation:
Again 6 times 7 is 42, but since one of them is negative it takes the negative sign making it -42
Solve the equation 3(5x-2)-3x=30
The answer is X=3, ur welcome :)
Answer: 3
Step-by-step explanation:
3(5x-2) - 3x = 30
15x - 6 - 3x =30
15x -3x = 30 + 6
12x = 36
X= 36/ 12
X = 3

Kelli has $33 in her checking account. She then writes a check for $42. What is the balance of Kelli's bank account?
Answer:
-9
Step-by-step explanation:
42-33= 9
But she is writing a check for $42 and only has $33 so that will send her into negatives.

Convert mixed number into improper fraction. For this : Multiply 3 and 2 and add 1. Also , remember that the denominator stays the same. ( i.e [tex] \sf{ \frac{3 \times 2 + 1}{2} = \frac{7}{2} } [/tex] )
⟼ [tex] \tt{ \frac{7}{2} \times \frac{1}{8}} [/tex]
To multiply one fraction by another , multiply the numerators for the numerator and multiply the denominators for its denominator.
⟼ [tex] \tt{ \frac{7}{16}} [/tex]
[tex] \pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \bold{ \tt{ \frac{7}{16}}}}}}}} [/tex]

State University has no honors English course but instead places all freshman scoring at least 60 on a proficiency exam (mean=50, standard deviation=10) into an advanced composition course. If the scores are normally distributed and there are 2,500 entering freshman, how many will be put into the advanced course?
Answer:
that put into the advanced course is 396.75
Step-by-step explanation:
The computation of that put into the advanced course is shown below:
P(X>60)
= P((X - mean) ÷ s > (60 - 50) ÷ 10)
= P (Z > 1)
= 0.1587
It could be checked by the standard normal table
Now that put into the advance course is
= 2,500 × 0.1587
= 396.75
Hence, that put into the advanced course is 396.75
Match the following words to the correct definition:
_____ translation ______ rotation ______reflection _____dilation
A. Flip B. Enlarge/reduce C. Turn D. Slide
Answer:
A. Flip ---> reflection
B. Enlarge/reduce ---> dilation
C. Turn ----> rotation
D. Slide ----> translation
Step-by-step explanation:
D and translation
A and reflection
C and rotation
B and dilation
it just makes sense.
dilation means like if you stung by a bee and it starts to swell but it can also be used as a way to say something shrunk.
reflection means yourself flipped
rotation means like your turning around or turning something around
i don't know if translation has anything to do with slide but it was the last option and all the others make sense.

Answer:
(Note: This is assuming that the answer can be in any format.)
[tex]y - 0 = -\frac{1}{3} (x - 3)[/tex]
Step-by-step explanation:
When given at least two points, you can find write an equation using the point-slope formula: [tex]y - y_1 = m (x - x_1)[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] are the x and y values from one point that need to be substituted in to make an equation, as well as the [tex]m[/tex] which represents the slope.
Find the slope by using the slope formula [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] and the two points given:
[tex]\frac{-1-0}{6-3}[/tex]
[tex]\frac{-1}{3}[/tex]
So, the slope is [tex]-\frac{1}{3}[/tex].
Next, choose a point (in this case, I chose (3,0)) and substitute its x and y values into [tex]x_1[/tex] and [tex]y_1[/tex] respectively, and also substitute [tex]-\frac{1}{3}[/tex] for m. This forms an equation of a line in point-slope formula:
[tex]y - 0 = -\frac{1}{3} (x - 3)[/tex]

Typed oral Question –
Each stand at the cricket stadium can seat 200 people. If there are 100 stands in the stadium.Create the multiplication problem using this information.
Answer:
If the stadium has 100 stands, it can accommodate 20,000 spectators.
Step-by-step explanation:
In order to determine the number of spectators that can enter the cricket stadium, knowing that it has 100 stands and that each of these has a capacity of 200 seated spectators, the following calculation must be performed:
200 x 100 = X
20,000 = X
Therefore, the cricket stadium has a capacity of 20,000 people seated.

Which inequality describes all the solutions to -5x + 6 < 2(-3 − x)?
Answer: x>4
Step-by-step explanation:
The solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.
The given inequality is 5x + 6 < 2(-3 - x).
What is a inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality can solved as follows:
5x + 6 < 2(-3 - x)
Multiply 2 to the bracket
5x + 6 < -6 - 2x
Add 2x to both the sides of inequality
5x + 6 + 2x < -6 - 2x + 2x
⇒7x+6<-6
Subtract 6 to both the sides of inequality
7x+6-6<-6-6
⇒7x<-12
Divide 7 to both the sides of inequality
7x/7<-12/7
⇒x<-12/7
⇒x<-1.7
Solution set = {-2, -3, -4, -5, -6,.......}
Therefore, the solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.

The Empirical Rule says that: Group of answer choices outliers are within three standard deviations of the mean. about 32 percent of the data are beyond one standard deviation from the mean most business data sets are normally distributed in most business data we expect the mean and median to be similar.
Answer:
The Empirical Rule says that:
outliers are within three standard deviations of the mean.
Step-by-step explanation:
An outlier is an observed data value which lies some abnormal distance from other values in a population's random sample. The cut-off for an outlier is three standard deviations from the mean in a normal distribution. Therefore, the Empirical Rule concludes that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean. In summary, the empirical rule concludes that 68% of the data falls within one standard deviation, 95% percent falls within two standard deviations, while 99.7% falls within three standard deviations from the mean.
A population has a mean of 110.22 and a standard deviation of 5.68. For which sample size does 95% of the sample means fall within the interval between 109.08 and 111.36?

Step-by-step explanation:
A survey was distributed to 2.000 employees and 90 percent of these employees responded to the survey. Of the employees responding, 60 percent answered "yes" to a certain yes-no question and 72 employees did not answer that question. How many employees answered "no" to this question?
Answer:
720 employees
Step-by-step explanation:
Number of responded employees = 90% of 2000 employees = 1800 employees
Out of 1800 employees, if 60% answer yes, then the remaining 40% will answer "no". 72 employees did not respond to the survey.
Number of "no" answered employees = 40% of 1,800 employees = 720 employees( Answer)
