Paul is making grey paint.

velikii [3]

Its quite simple. for every white bucket of paint he uses, he uses 3 buckets of black paint as well. so if he made 24 litres of grey paint then he would have had to use 24 buckets of white paint. but, this might be a trick question because its saying he made 24 "litres" but the unit it started with was "buckets" so it might be trying to trick you because we dont know how much paint is in one "bucket"

On a bicycle trail, the city is painting arrows like the one shown below: Upper pointing arrow with height of 15 and length of 1

Luden [163]

Answer:

229.5 $cm^{2}$

Step-by-step explanation:

In order to calculate the area of the arrow we need to calculate the area of the body of the arrow, and then the head of the arrow. The body of the arrow is a rectangle meaning that the area (Ar) can be calculated by multiplying the length by the height like so...

Ar = l * h

Ar = 11cm * 12cm

Ar = 132 $cm^{2}$

Now we need to find the area of the head of the arrow, which is a triangle and therefore we can use the formula for the area of a triangle (At) which is height times base divided by 2...

At = $\frac{h * b}{2}$

At = $\frac{15cm * 13cm}{2}$

At = $\frac{195cm^{2} }{2}$

At = 97.5 $cm^{2}$

Now we simply add both areas together to calculate the total area of the arrow...

132 $cm^{2}$ + 97.5 $cm^{2}$ = 229.5 $cm^{2}$

Part A:

Given that 47% of adults prefer milk chocolate to dark chocolate, for a random sample of n = 4 adults, the probability that all four adults say that they prefer milk chocolate to dark chocolate is given by

$P(4)=(0.47)^4=0.049$

Part B:

The probability that exactly two of the four adults say they prefer milk chocolate to dark chocolate is given by

$P(2)={ ^4C_2(0.47)^2(1-0.47)^2} \\ \\ =6(0.2209)(0.2809)=0.372$

Part C:

The probability that at least one adult prefers milk chocolate to dark chocolate is given by

$P(at \ least \ 1)=P(X\geq1) \\ \\ =P(1)+P(2)+P(3)+P(4) \\ \\ =1-P(0)=1-{ ^4C_0(0.47)^0(1-0.47)^4} \\ \\ =1-(0.53)^4=1-0.0789=0.921$
