Answer:
84
Step-by-step explanation:
A rhombus has parallel sides so it's simply
24+24+18+18=84
Answer:
The two solutions to the equation are x = 14/3 or x = -16/3
Step-by-step explanation:
To find these values, go through the steps of solving an equation as if the absolute value symbol is just a parenthesis.
4|x + 1/3| = 20
|x + 1/3| = 5
Now that we have it down to just this, we know what is inside the absolute value symbol to be either +5 or -5. So we need to solve this twice using each option.
x + 1/3 = 5
x = 14/3
x - 1/3 = -5
x = -16/3
Answer:
c = 60
Step-by-step explanation:
A triangle = 180 degrees
180-(15+105)=c
c=60
45 1/2
Take 2*45 and add 1
91/2
Answer:
1.4% of connectors fail during the warranty period.
Step-by-step explanation:
We have these following probabilities:
A 90% probability that a connector is kept dry.
A 10% probability that a connectors is wet.
If a connector is dry, an 1% probability of failling.
If a connector is wet, a 5% probability of failling.
What proportion of connectors fail during the warranty period?
This is 1% of 90% and 5% of 10%. So
1.4% of connectors fail during the warranty period.
