Answer: a^2+3a+2
Step-by-step explanation:
if you do the distribution method and do (a*a)+(a*2)+(1+a)+(1*2)=(a^2)+(2a)+(a)+(2)
which you get a^2+3a+2
Had to do a bit of guesswork to figure out what you're asking here. If you're given the 2 angles pi/4 and pi/6, you can find any trig function of either angle.
The sine of pi/4 is 1 / sqrt(2); the cosine is the same.
The cosine of pi/6 is sqrt(3) / 2; the sine of pi/6 is 1/2.
If this isn't quite what you were looking for, try paraphrasing your question to make it clearer.
You cross multiple. Remember 5 = 5/1
So x/2 = 5/1
Cross multiple x is linked with 1 and 2 is lined with 5.
So x(1) = 5(2)
X = 10
Answer:
The probability a random selected radish bunch weighs between 5 and 6.5 ounces is 0.8185
Step-by-step explanation:
The weight of the radish bunches is normally distributed with a mean of 6 ounces and a standard deviation of 0.5 ounces
Mean = 
Standard deviation = 
We are supposed to find the probability a random selected radish bunch weighs between 5 and 6.5 ounces i.e.P(5<x<6.5)

At x = 5

Z=-2

At x = 6.5

Z=1
Refer the z table for p value
P(5<x<6.5)=P(x<6.5)-P(x<5)=P(Z<1)-P(Z<-2)=0.8413-0.0228=0.8185
Hence the probability a random selected radish bunch weighs between 5 and 6.5 ounces is 0.8185
1) 140/4=. or. 140/.25
2) $282 x 1.04=. 1 being the price; .04 the tax
3) 650x 1.1=. 1 being Fri. attendance .1 the 10% increase on Saturday
