In the evening, the temperature is 28 degrees. By midnight it has dropped 31 degrees lower. Between midnight and 4 am it goes down 6 more degrees. Then, by 9 am, the temperature goes up 30 degrees. What is the temperature at 9 am?

Answers

Answer 1

Answer: 21 degrees

Step-by-step explanation:

In the evening, the temperature is 28 degrees and by midnight it has dropped 31 degrees lower, the temperature by midnight will be:

= 28° - 31°

= -3°

Between midnight and 4 am it goes down 6 more degrees. The temperature by 4am will be:

= -3° - 6°

= -9°

Then, by 9 am, the temperature goes up 30 degrees, the temperature at 9 am will then be:

= -9° + 30°

= 21°

In a batch of 700 recently manufactured items, what is the expected number of defective products?

Answers

Answer:

11

Step-by-step explanation:

Change 1.5% to a decimal which equals 0.015

Multiply 700 by 0.015 which equals 10.5

Since you can't have half a defective product you round

in the sequence 34, 40, 37, 36, 42, 39, 38’…, what numbers should come next?
a) 44, 42 , 41
b) 43, 40, 39
c) 45, 42, 41
d) 44, 41, 40

Answers

Answer:

d) 44, 41, 40

Step-by-step explanation:

34 + 6 = 40

40 - 3 = 37

37 - 1 = 36

36 + 6 = 42

42 - 3 = 39

39 - 1 = 38

pattern: +6, -3, -1

the next pattern from -1 is +6 so we take 38 and add 6:

38 + 6 = 44

then take 44 and subtract 3 from it:

44 - 3 = 41

lastly, take 41 and subtract 1 from it:

41 - 1 = 40

Answer:

44,41,40

Step-by-step explanation:

34

34 + 6 = 40

40 - 3 = 37

37 - 1 =  36

36 + 6 = 42

42 - 3 = 39

39 -1 = 38

So, your next set of numbers are

38 + 6 = 44

44 - 3  = 41

41 - 1 = 40

Which stemplot correctly shows the number of minutes to complete a quiz? Check all that apply. 11, 12, 13, 14, 15, 16, 17, 19, 25, 25, 26, 27, 28, 29, 31, 32, 33, 35, 38, 39
Use this graphic to answer the question.​

Answers

Answer:B and C

Step-by-step explanation:

The correct stemplot is:

1: 1 2 3 4 5 6 7 9

2: 5 5 6 7 8 9

3: 1 2 3 5 8 9

What is the stemplot?

A stem-and-leaf display or stem-and-leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution.

So for given number of minutes to complete quiz we sort them out as :

11, 12, 13, 14, 15, 16, 17, 19, 25, 25, 26, 27, 28, 29, 31, 32, 33, 35, 38, 39

The stem is then written in a vertical column. Each leaf is written in the row to the right of its stem

In the data above, 13

1 is the stem

3 is the leaf

to make a stemplot.

1: 1 2 3 4 5 6 7 9

2: 5 5 6 7 8 9

3: 1 2 3 5 8 9

which is the correct stemplot for the given minutes where colon sign is used to indicate the column.

Thus the correct stemplot is:

1: 1 2 3 4 5 6 7 9

2: 5 5 6 7 8 9

3: 1 2 3 5 8 9

The initial value of the exponential function is 2.

What are Exponential Functions?

Exponential functions are functions where the independent variable, x is in the exponent.

Given is the graph of the exponential function.

The initial value of the exponential function is the value of the function  when the value of the independent variable is 0.

The general form of exponential function is y = abˣ

When x = 0, y = a, which is the initial value.

Here, when x = 0, the graph touches the Y axis.

y = 2

Hence the initial value is 2.

Answer:

the possible line of best fit equation is;

y = 10x + 24

Step-by-step explanation:

Here, we want to get the approximate line of best fit

Mathematically, we have the general line of best fit as

y = mx + b

where m is the slope and b is the y-intercept

By joining the given lines, we can see that the y-intercept values fall a little below 30

This means that the possible y-intercept value is 24

Now, to get the slope value, we select any two points and use the slope equation

We can have (3,50) and (6,80)

Using the slope equation;

m = (y2-y1)/(x2-x1) = (80-50)/(6-3) = 30/3 = 10

The equation is thus;

y = 10x + 24
