Answer:

Present salary is 550

Step-by-step explanation:

Here, we want to calculate the present salary seeing that it was 10% added to what we had last year

mathematically, that will be;

10/100 * 500 = 50

Adding this to 500, his present salary is 50 + 500 = 550

The midpoint of RS is M(1, 2). One endpoint is R(-6, 6). Find the coordinates of endpoint S.

AysviL [449]

Answer:

The coordinates of point S are (8,-2)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

$M=(\frac{x1+x2}{2},\frac{y1+y2}{2})$

Let

Point S(x2,y2)

substitute the given values

$(1,2)=(\frac{-6+x2}{2},\frac{6+y2}{2})$

<em>Solve for x2</em>

$1=(-6+x2)/2\\2=-6+x2\\x2=2+6=8$

<em>Solve for y2</em>

$2=(6+y2)/2\\4=6+y2\\y2=4-6=-2$

therefore

The coordinates of point S are (8,-2)

If represented in a stem and leaf plot, what would be the leaf of the number 329?

sdas [7]

Answer:

You can either do a back to back stem and leaf plot, where you would have double the values. In a normal stem and leaf plot you would just have one set of 3's where you would put all the values that start with 3 in that column. A back to back is the same but instead you would have two 3 values, where anything that is higher than 5 would be in the second value of 3, but anything lower would be in that first value of 3.

A study of the checkout lines at the Safeway Supermarket in the South Strand area revealed that between 4 and 7 P.M. on weekdays

Dima020 [189]

Answer:

Step-by-step explanation:

Given that a study of the checkout lines at the Safeway Supermarket in the South Strand area revealed that between 4 and 7 P.M. on weekdays there is an average of four customers waiting in line.

Let X be the number of customers waiting in line

X is Poisson with parameter = 4

the probability that you visit Safeway today during this period and find:

a. No customers are waiting

$P(X=0) = 0.018316$

b. Four customers are waiting?

$=P(x=4) =0.193567$

c. Four or fewer are waiting?

= $P(X\leq 4) = 0.628837$

d. Four or more are waiting

= $P(X\geq 4)=0.56653$

Alyssa had 45$ to spend on 6 snacks.after buying them she had 12$ left how much did each snack cost?

Radda [10]

Each snack cost $5.50

You start with $45, and afterwards end up with $12, so subtract 12 from 45 and you end up with 33. Then divide 33 by 6, since she bought 6 snacks, and you get $5.50.
