Simran used a simulation to predict the number of days of rain in his town. A number 1 or 2 indicates a week in which it rained. Numbers 3, 4, or 5 indicate a week in which it did not rain. The results of the simulation are shown above. What is the experimental probability that it will rain in Simran’s town in at least 1 of the next 4 weeks?

Answer: $13.30

Step-by-step explanation:

price of nails = $1.30/lb

price of washers = $0.80/lb

price of bolts = $2.50/lb

The total cost of buying 2 pounds of nails, 4 pounds of washers, and 3 pounds of bolts will be:

= (2 × $1.30) + (4 × $0.80) + (3 × $2.50)

= $2.60 + $3.20 + $7.50

= $13.30

The total cost is $13.30

Answer:

Laura needs to try 36 more times before the lock is sure to open.

Step-by-step explanation:

Alright, with a three digit lock, there are 9 possible numbers for each digit:

1, 2, 3, 4, 5, 6, 7, 8, and 9.

Since the first one is 3, lets move onto the second digit, which is prime.

Of the numbers between 1-9,

2, 3, 5, and 7 are prime.

With the last digit, it can be any number 1-9.

With all of this, there are 4 combos left for the second digit then 9 combos for the third digit. Therefore, there would be 36 possible combinations as 4 * 9 =36.

Answer:

(-.5,0) and (-1.5,0)

or b= -.5

and b= -1.5

Step-by-step explanation:

First we want one side of the equation to equal 0

we have

4b²+8b+3=0

using the quadratic formula we have

(-b±√(b²-4*a*c))/2a

(-8±√(8²-4*4*3))/2*4

(-8±√(16))/8

(-8±4)/8

now we evaulate when ± is addition

(-8+4)/8

-4/8

-.5

and evaulate once more when the ± is subtraction

(-8-4)/8

-12/8

-1.5

Therefore the two solutions are (-.5,0) and (-1.5,0)

Answer:

Step-by-step explanation:

step one - Move terms to the left side

(4b^2 + 8b + 7 = 4)

(4b^2 + 8b + 7 - 4 = 0)

step dose - Subtract the numbers

(4b^2 + 8b + 3 = 0)

step три - Use the sum-product pattern

(4b^2 + 6b + 2b + 3 = 0)

Step-by-step explanation:

because 24.56 / 5 = 4.912

4.912*4=19.648

Answer: Length = 10cm

Width = 6.5cm

Step-by-step explanation:

Let the width of the rectangle be represented by x.

Therefore, the length of the rectangle will be: = (2 × x) - 3 = 2x - 3

Therefore area of a rectangle = length × width

x(2x - 3) = 65

2x² - 3x = 65

2x² - 3x - 65 = 0

2x² + 10x - 13x - 65 = 0

2x(x + 5) - 13(x + 5) = 0

(2x - 13)(x + 5) = 0

2x - 13 = 0

2x = 13

x = 13/2

x = 6.5

Width = 6.5cm

Length = 2x - 3

= 2(6.5) - 3

= 13 - 3

= 10cm

Therefore, the length of the rectangle is 10cm and the width is 6.5cm.

In bottle 1/4 of chlorine solution is left in bottle.

What is an expression?

Expression in math is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that;

Felicia pours 3/4 of a 2 1/2-liter bottle of chlorine solution into a swimming pool.

And, then she measures out 3/8 liters of the remaining solution to use to clean the pool filter.

Now,

Chlorine solution in bottle = 2 1/2 × ( 1 - 3/4 ) - 3/8

                                        = 5 / 2 × 1/4 - 3/8

                                        = 5 / 8 - 2 / 8

                                        = 1 / 4

Thus, In bottle 1/4 of chlorine solution is left in bottle.

Graph included as picture

Step-by-step explanation:

To solve this, plot the given points on the graph

Draw a line through them.

Now select two of those values and we'll find the rate of change.

We'll be using (1,-1) and (3,3)

To find rate of change we will be using the formula: [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

[tex]y_{2} = 3\\y_{1} =-1\\x_{2} = 3\\x_{1} = 1[/tex]

[tex]\frac{3-(-1)}{3-1} = \frac{4}{2} = 2[/tex]

So the rate of change is 2

You will use this rate of change for your other function because they both have the same rate of change

Since we have the rate of change, we can create the slope intercept form formula: y = mx +b

Just substitute for the variables we know

m = rate of change/slope = 2

b = y-intercept = -3

y = 2x + -3

[If you connected all the points in your graph, that's how you found the y-intercept]

Now we have to create the formula for the second function.

We know it will have that same slope of 2

so we have y = 2x + b

To solve for b we can plug in the values we do have which would be (x,y) of (3,6)

6 = 2(3) + b

Now solve

6 = 6 + b

6 (-6) = 6 (-6) + b

0 = b

b = 0

This mean that the y-intercept will be on (0,0)

Plot that point

Now we finish the formula

y = 2x + 0

Connect the dots, make sure the line continues on both of them past the dots and now you have your graph!

I've included a picture of the graph for your reference. I hope this helps, don't be afraid to reach out with further questions!

Step-by-step explanation:

The question is incomplete, as the histogram is not attached.

However, the solution to your question is to select the interval with the highest frequency

Take for instance, after getting readings from the histogram, yiu have:

1 - 10: 8

11 - 20: 5

21 - 30: 11

31 - 40: 2

And so on.......

Interval 11 - 20 will represent the required interval because it has the highest frequency.

Answer:

804.25

Step-by-step explanation:

The area of a circle = pi(r)^2

Given the diameter, we can find the radius by dividing the diameter in half.

r=16

pi(16)^2 = 804.25

Answer:

803.84 OR 256 pi

Step-by-step explanation:

Ok!

Step 1:

The area of a circle is Pir^2. (Sorry it’s pi r squared, I don’t have the pi symbol or the exponent function on my iPad.)

R is radius. Remember, radius is half the diameter.

32/2=16.

Step 2:

Do 16^2.

You should get 256.

Step 3:

Multiply 256 by Pi. Pi is 3.14. You should get 803.84.

Step 4:

803.84 should be the answer, I THINK (not sure) you can also write your answer as 256 pi. Depends on what your teacher wants. Hope this helps! Next time you can search up how to find the area of a circle, there are lots are tutorials!
