Answer:
3:4
4:5
Step-by-step explanation:
The ratios are ...
short side : long side = 12 : 16 = 3 : 4
and for the other rectangle, ...
short side : long side = 8 : 10 = 4 : 5
_____
To reduce the ratio to lowest terms, divide each number by their greatest common factor. 12 and 16 have a common factor of 4: 12=4·3, 16=4·4. 8 and 10 have a greatest common factor of 2.

Answer:
-7+4=-3
Step-by-step explanation:
Think of it as adding head to cold (cold being negative numbers). You are adding four "heats" to seven which makes it hotter. The hotter something gets the closer to positive numbers it is. . . so when adding four things if heat to 7 it gets hotter by four therefore it's now at -3.
sorry if that didn't make sense
Answer:
0.98046
Step-by-step explanation:
Given:
Here we are required to find
P(5.48 <X<5.82) and between 5.48 and 5.82 we each z-score given by
<em>z = (x - μ) / σ</em>
So 5.48 we have z = -2.714 and 5.82 we have z = 2.143
Therefore we have the area of interest on the normal distribution chart given by
:
P( -2,714 < z < 2.143)
= 1 - P(Z<-2.714) + P(Z > 2.143)
= 1 - P(Z<-2.714) + (1 - P(Z < 2.143))
= 1 - 0.00336 + 1 - 0.98382
= 1 - 0.01954 = 0.98046
