write down three integers, all less than 25 whose range is 10 and mean is 13

Answers

Answer 1

Answer:

Step-by-step explanation:

we have the mean=13

(x+y+z)/3=13

x+y+z=39

range=highest value-lowest value=10

lets say x= highest value

y=lowest value

x-y=10

x=10+y

the numbers are 9,11,19

19-9=10 range

sum is 39

additional fee of $20 for equipment transportation.
A. Write an equation in slope-intercept form for this
situation
B. Il your total bill was S155, how long did the worker fix
your yard?
C. If the lawncare worker works a full 8-hour shift, how
much does he make

Answers

A.Slope- intercept form is y= Mx+b so y= 45x + 20

B. 3 hours;
155=45x+20
155 -20 = 135
135/45 = 3

C. $380
y= 45(8)+ 20
45*8= 360

Three coins are tossed simultaneously 350 times. The distribution of various outcomes is listed below :Outcome3 Tails2 Tails1 TailNo TailsNo. Of times65 95 110 80 respevtove;y Compute the probability of getting:(i)At least 1tail(ii) Exactly 3 heads

Answers

Answer:

(i) [tex]\frac{27}{35}[/tex]

(ii) [tex]\frac{8}{35}[/tex]

Step-by-step explanation:

Probability refers to chances of occurrence of any event.

Probability is calculated by dividing number of favorable outcomes by total number of possible outcomes.

Total number possible of outcomes = 350

(i)

Number of favorable outcomes = [tex]65+95+110=270[/tex]

Probability [tex]=\frac{270}{350}=\frac{27}{35}[/tex]

(ii)

Exactly 3 heads is equivalent to no tails.

Number of favorable outcomes = [tex]80[/tex]

Probability [tex]=\frac{80}{350}=\frac{8}{35}[/tex]

Answer:

-17√2 /26 or -0.9247 to the nearest ten thousandth.

Step-by-step explanation:

The hypotenuse of the right triangle in which tan x = 2/3 is √(2^2 + 3^2)

= √13 so sin x = 2/√13 and cos x = 3/√13

sin2x = 2sinxcos

= 2* 2/√13 * 3/√13

= 12/13.

cos2x = cos^2x - sin^2x

= 9/13 - 4/13

= 5/13.

sin(2x + 5π/4)

= sin2x cos5π/4 + cos2x sin5π/4

= 12/13 * -1/√2 + 5/13 * -1/√2

= -12 / 13√2  - 5 / 13√2

= -17/13√2

= -17√2 /26.

Work out the size of angle x
Next to 164 and 90

Answers

Answer:

x=106 degrees

Step-by-step explanation:

I'm going to assume that this is a circle since you didn't give it to me

So you want to add 164 and 90 together and subtract the sum by 360

360-(164+90)=106

So you want to use PEMDAS (order of operations) to solve this

so do what's in the perenthesis first so 164+90=254Then you want to subtract 254 from 360 so 360-254=106

x=106 degrees

Answers

Answer:

7 pounds for 3.25

Step-by-step explanation:

7 pounds of apples is alot for a cheap price like 3.25

5lbs for $2.89 because 5x2.89=14.15 and 7x3.25=22.75, and $14.15 is cheaper than $22.75

A worker on the production line is paid a base salary of ​$170 per week plus ​$1.21 for each unit produced. Write an equation to represent his earnings of ​$491.86 for a week when he produced x units. How many units did he ​produce? Use pencil and paper. If the worker had produced twice that number of​ units, what would his earnings have​ been? Show your work.

Answers

Answer:

Part 1)

$170 + $1.21x = $491.86

Part 2)

170 + 1.21x + 491.86

1.21x = 491.86 - 170

1.21 x = 321.86

1.21x/ 1.21 = 321.86/ 1.21

x = 266 units produced

Part 3)

Twice that number of units = 266 x 2 = 532

$170 + ($1.21 x 532) =

$170 + $643.72 = $813.72

Answers

Answer:

Option A

Step-by-step explanation:

Option A

f(x) = -3(x + 7)(x + 4),

Remember that to solve for the x-intercepts we equate y to 0,

-3(x + 7)(x + 4) = 0

Using the zero product property,

x + 7 = 0, x + 4 = 0

x = - 7, x = -4

x -intercepts: (- 7, 0) & (- 4, 0)

Hence proved.

estimate a 15% on a dinner bill of $42.58 by first rounding the bill amount to the nearest ten dollars

Answers

Answer:

$6

Step-by-step explanation:

Round $42.58 to the nearest ten dollars to get $40. $40 ÷ 100 = $0.4 so this is one percent. $0.4 × 15 is $6 which is an estimate of 15% of $42.58.

The answer is $6 (unless if you are meant to add this to $42.58 - then the answer would be $48.58 - but I am not sure because of the wording of the question).
