Answer:

Step-by-step explanation:

z(lower) = (15-15)/4 = 0

z(upper) = (19-15)/4= 1

z  at  0 = .5

z at  1 = 0.841344746

(look these up in a Z table)

probability "between" = 0.841344746 - .5 = 0.3841344746

iris [78.8K]

Hello from MrBillDoesMath!

Answer:

15

Discussion:

Given: measure angle STQ = 7x + 55.  But, as shown, STQ is a right angle so

7x + 55 = 90          => subtract 55 from each side

7x = 90 -55 = 35   => divide each side by 7

x = 35/7 = 5

Since RS = (x+1)    + (2x-1)  where x = 5.

     RS = (5 + 1) + (2*5 -1)

           = 6         + 9

           = 15

I don't know what choice the answer is as your diagram only shows Choice A

Thank you,

MrB

Ryan spent $26.32 on 8 gallons of<br> gas. How much would he spend<br> for 20 gallons?
Nana76 [90]

Answer:

$65.80

Step-by-step explanation:

Divide 26.32 by 8 to find how much is in one gallon.

26.32÷8=3.29

So it's 3.29 per gallon.

Multiply 3 29 by 20.

20×3.29= 65.8

How many cubes of edge 4cm, each can be cut out from cuboid whose length, breadth and height are 20 cm, 18 cm and 16 cm respecti
My name is Ann [436]

Answer:

90 cubes.

Step-by-step explanation:

First we find volume of the cuboid.

Volume = l x b x h = 20 x 18 x 16 = 5760 cm³

Now,

Volume of a single cube = l³ = 4³ = 64

No of cubes that can be cut out from the cuboid is

= Volume of cuboid/ volume of cube

= 5760/ 64

= 90 cubes
