Mathematics
1 answer:
Andre45 [30]2 years ago
6 0

Answer:

.0853

.8770

.9370

.0045

.4898

Step-by-step explanation:

Just go to a ztable and match the values (I've attached the one i use below)

if it's negative subtract one

if it's z># then subtract one

so for 1.37 go to the table and find the value (.8770) and subtract 1

Go to 1.16 on the z table (.8770), subtract 1 (1-.8770) and then do it again

for the last one you need to take a z value of 0 (.5) and then the value for 2.32 (.9898) and subtract them

.9898-.5=.4898

Any ideas on how to find the value of 'x' on either 13 or 16? Anything helps!
Artemon [7]
(x+5)/4=1/2
first get rid of the fraction
multiply both sides by 4
x+5=2
subtract 5
x=-3

(2x+1)/(4x-1)=2/3
get rid of the fractions,
multiply both sdies by (4x-1)(3)
(2x+1)(3)=(2)(4x-1)
distribute
6x+3=8x-2
subtract 6x form both sdies
3=2x-2
add 2
5=2x
divide by 2
5/2=x

PLEASE HELP ME ON THIS!!
Ganezh [65]

Answer:

-6

Step-by-step explanation:

This means what value can I plug into -3x-8 so that I get output 10.

g(x)=-3x-8

g(a)=-3a-8

So we are going to solve g(a)=10 for a.

g(a)=10

-3a-8=10

Add 8 on both sides:

-3a   =18

Divide both sides by -3:

 a     =-6

Check it!

g(-6)=-3(-6)-8=18-8=10 and it's good! :)

Calculate the length of an arc
jek_recluse [69]
Easy peasy
remember that the arc is a part of the perimiter of the circle aka circumference
also 360 degrees=circle

we are given the radius
calculate circumference
c=2pi times r
r=14
c=pi times 2 itimes 14
c=28pi

100 degrees is the arc

find what fraction of the circumferece thei srepresents
whole=360
100/360=10/36=5/18
so if circumference=28pi then multiply 5/18 by that
5/18 times 28pi=140pi/18=70pi/9
legnth=(70pi)/9 cm
if you were to aprox pi to 3.14 then the answer would be
24.4222222 cm
