How do I solve this math problem 53x6=6x53=

AlladinOne [14]

You only need to solve one part of the problem, because the second problem is the exact same as the first, so you would do 53 x 6= 318, and 6 x 53 also equals 318

Can someone answer #9

In-s [12.5K]

Solution:

First i'm going to divide the graph into 3 parts. Linear, Quadratic and Horizontal graph.

Linear:

$Slope=\frac{-2-0}{-4-(-2)}=1\\y=m(x-xo)+yo\\y=1x-(-2)+(-4)\\y=x-2 , x\leq-1$

Quadratic:

$f(x) = a(x-h)^{2} + k\\f(x)=(x-2)^{2}-7,-1\leq x\geq 6$

Horizontal:

$f(x)=7,x\geq 6$

Answer:

$f(x)=x-2 , x\leq-1\\f(x)=(x-2)^{2}-7,-1\leq x\geq 6\\f(x)=7,x\geq 6$

Hope this was helpful.

The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 256.3 and a standard deviation of

AnnyKZ [126]

Answer:

a) In the interval ( 55,9 ; 456,7 ) we will find 99,7 % of all values

b) In the interval ( 122,7 ; 389,9 ) we find 95,4 % of all values

Step-by-step explanation:

For a Normal distribution N (μ ; σ ) the Empirical rule establishes that the intervals:

( μ ± σ ) contains 68,3 % of all values

( μ ± 2σ ) contains 95,4 % of all values

( μ ± 3σ ) contains 99,7 % of all values

If N ( 256,3 ; 66,8 )

σ = 66,8 ⇒ 3*σ = 3 * 66,8 = 200,4

Then: 256,3 - 200,4 = 55,9

And 256,3 + 200,4 = 456,7

a) In the interval ( 55,9 ; 456,7 ) we will find 99,7 % of all values

b) 2*σ = 2 * 66,8 = 133,6

Then 256,3 - 133,6 = 122,7

And 256,3 + 133,6 = 389,90

Then in the interval ( 122,7 ; 389,9 ) we find 95,4 % of all values
