I need help!!! Solve the equation 7= -10s -3

Mathematics
1 answer:
mojhsa [17]2 years ago
6 0

Answer:

s = -1

Step-by-step explanation:

7 = -10s -3 <== add 3 to both sides

+3        + 3

10 = -10s <== divide both sides by -10

/-10    /-10

-1 = s

Final answer: -1 = s  or  s = -1

Hope this helps!

A survey of several 9 to 11 year olds recorded the following amounts spent on a trip to the mall: $23.71,$17.79,$29.87,$18.78,$2
wolverine [178]

Answer:

(16.904 ; 30.660)

Step-by-step explanation:

Given the data :

X = 23.71,17.79,29.87,18.78,28.76

Sample size = 5

Mean = (23.71+17.79+29.87+18.78,+28.76) / 5 = 23.782

Using a calculator, sample standard deviation :

Standard deviation, s = 5.54

Tcritical at α = 0.05, df = 5 - 1 = 4

Using tables ; Tcritical value = 2.7763

Confidence interval :

Mean ± Margin of Error

Margin of Error (MOE) = Tcritical * SE

Margin of Error = Tcritical * s/sqrt (n)

MOE = 2.7763 * 5.54/Sqrt(5) = 6.878

Confidence interval : 23.782 ± 6.878

Lower boundary : 23.782 - 6.878 = 16.904

Upper boundary = 23.782 + 6.878 = 30.66

(16.904 ; 30.660)

The height of a right cylinder is 2r, where r is the radius. Write a function f in simplest form that represents the ratio of th
makkiz [27]
F = 3/r.

The formula for the volume of a cylinder is

V=πr²h.  We know that h=2r, so this gives us:

V = πr²(2r) = 2πr³

The surface area of a cylinder is the sum of the areas of all of the faces.  The bottom and top are circles, whose areas are both given by A=πr².  The lateral area of a cylinder is given by the circumference multiplied by the height.  C = 2πr, and the height is 2r, so the lateral area would be

A=(2πr)(2r)= 4πr².  This gives us a total surface area of

SA = 4πr²+πr²+πr² = 6πr².

The ratio of surface area to volume would be:

SA/V = 6πr²/2πr³.  After simplifying, we have f=3/r.

What is the decimal expansion of 10/11
Novay_Z [31]

Answer:

To write 10/11 as a decimal you have to divide numerator by the denominator of the fraction. We divide now 10 by 11 what we write down as 10/11 and we get 0.90909090909091 And finally we have: 10/11 as a decimal equals 0.90909090909091
