The sum of two numbers is 50. The first number is 18 less than the 2nd number. What are the
2 numbers?

Answers

Answer:

2y + 2 + y = 50 (combine like terms)

3y + 2 = 50

3y = 50 - 2

3y = 48

y = 16

Substitute 16 for y in either equation 1 or 2 and solve for x (I chose equation 1):

x + 16 = 50

x = 50 - 16

x = 34

You intend to estimate a population mean μ with the following sample. 78.4, 85.3, 50, 68.4, 59.4, 73.7, 73.2, 47.4, 40.5
You believe the population is normally distributed.
Find the 99.5% confidence interval.
The answer must be done as an open-interval accurate to 2 decimal places.

Answers

Answer:

(17.75, 110.32)

Step-by-step explanation:

The sample mean is 64.03, and the standard deviation is 15.43.

The population is normally distributed, so 99.5% confidence is ±3 standard deviations.

The confidence interval is therefore:

(64.03 − 3 × 15.43, 64.03 + 3 × 15.43)

(17.75, 110.32)

The 99.5% confidence interval will be equal to  (17.75, 110.32).

What is Probability?

Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.

As per the given data provided by the question,

With a standard deviation of 15.43 and a sample mean of 64.03, respectively.

Since the population has normally distributed, 99.5% probability lies within a range of three standard deviations.

Consequently, the confidence interval is:

= (64.03 − 3 × 15.43, 64.03 + 3 × 15.43)

= (17.75, 110.32), this is up to 2 decimal places.

A pendulum swinging through a central angle of 108° completes an arc of length 24 cm. What is the length of the
pendulum? Round to the nearest hundredth.

Answers

Answer:

Yes! I was looking to refresh my geometry skill!

Step-by-step explanation:

So, a 108* arc is 24 cm. How to solve it?

First, we need to find the Circumference, or perimeter of the circle. (That the swinging pendulum makes.

Second, use that in the formula for circumference, and find the radius.

Third, done! So, let's get to it!

All we have to do to find the circumference is divide 24 by 108, then multiply that by 360*(because a circle is 360*).

[tex]24/108*360=80[/tex]

So, our circumference is 80cm. Nice! Just need to input that into the circumference formula.

[tex]80=2\pi *r\\[/tex]

Now, to solve...

[tex]40=\pi *r\\40/\pi =r[/tex]

This rounds to about 12.73 cm.

Hope this helps!

Find the slope, if it exists, of the line containing
(-8,-5) and (-19,- 13)

Answers

Answer: 8/11

Step-by-step explanation:

To find slope you can use this formula:

y2-y1/x2-x1

substitute the values with the ones from the 2 points

-13-(-5)= -8

-19-(-8)=-11

you then divide -8/-11

and you get 8/11

8/11 is the slope of those 2 points.

Rhonda had $300 to buy supplies for the animal shelter. She bought 8 bags of dog food and 11 leashes. Each bag of food cost $25.19, and each leash cost $4.65. How much money did Rhonda have left after her purchases? $11.65 $14.29 $22.91 $47.33

Answers

Hey there! I'm happy to help!

We have 8 bags of dog food and each costs $25.19

8(25.19)=201.52

And we have 11 leashes each costing $4.65.

11(4.65)=51.15

We add these totals up.

201.52+51.15=252.67

We subtract this from 300 to see how much is left.

300-252.67=47.33

Rhonda had $47.33 left after her purchases.

Have a wonderful day! :D

Answer:

$47.33

Step-by-step explanation:

she bought 8 bags of dog food so: 8 x 25.19 = 201.52

she bought 11 leashes so: 4.65 x 11 = 51.15

201.52 + 51.15 = 252.67

300 - 252.67 = 47.33

Slope = -9

y-intercept = 5

A steel woodworking blade is created from a rectangular mold with vertices at (0, 0), (0, 1), (4, 0), and (4, 1). (All coordinates are in centimeters). At each point of the blade, the thickness, in milimeters, is equal to twice the y-coordinate. Find the height of the balance point of the blade.

Answers

Answer:

5.6 cm

Step-by-step explanation:

Given that a steel woodworking blade is created from a rectangular mold with vertices at (0, 0), (0, 1), (4, 0), and (4, 1). (All coordinates are in centimeters). At each point of the blade, the thickness, in milimeters, is equal to twice the y-coordinate. 

The x axis or the horizontal length will be L = (1 - 0)^2 + ( 0 - 0 )^2

L = 1 cm

The y axis or the vertical length will be

L = sqrt ( [ 4-0]^2 + [0-0]^2)

L = Sqrt(16)

L = 4 cm

Given that at each point of the blade, the thickness, in milimeters, is equal to twice the y-coordinate.

That is,

Thickness = 2 × 4 = 8 mm

The height of the balance point of the blade will be;

Height = 8 mm + 4 cm + 8 mm

Height = 0.8 + 4 + 0.8

Height = 5.6 cm

Note that the thickness will be added to both the top and the bottom of the blade.

A car's rear windshield wiper rotates 140°. The total length of the wiper mechanism is 24 inches and the length of the wiper blade is 16 inches. Find the area wiped by the wiper blade. (Round your answer to one decimal place.)

Answers

Answer:

312.7 in^2

Step-by-step explanation:

This problem is on the mensuration of flat shapes, sectors and arc.

we know that the area of a sector is given as

A=(∅/360)*πr^2

Given that the length of the wiper R=24 in

and the length of the blade r= 16in

To find the area of the wiped surface we only require the length of the blade as the radius

The area of the wiped surface is given as= (140/360)*3.142*16^2

A= 0.3888*3.142*256

A=312.7 in^2
