Answer:
Part 1)
Projection of vector A on vector B equals 19 units
Part 2)
Projection of vector B' on vector A' equals 35 units
Step-by-step explanation:
For 2 vectors A and B the projection of A on B is given by the vector dot product of vector A and B
Given

Similarly vector B is written as

Thus the vector dot product of the 2 vectors is obtained as

Part 2)
Given vector A' as

Similarly vector B' is written as

Thus the vector dot product of the 2 vectors is obtained as

<span>Lisa and Bart spin this spinner 60 times the result are below/ black=17 blue=15 orange=21 purple=7 a. What is the experimental probability of a spin of orange? B which color had an experimental probability that matched its theoretical probability
<u>Answers</u>
a) 0.35
b)Blue
<u>Explanation</u>
The probability of an event is its chance to occur.
Probability is found by the formula,
Probability = (Number of favourable outcome)/(Number of total outcome)
Part a
</span>The orange are 21 and the total spins are 60.
Probability (orange) = 21/60
= 0.35
Part 2
The theoretical probability of blue is normally 25%.
By calculating the experimental probability of blue we get,
P(blue) = 15/60
= 1/4
In percentage
1/4×100 = 25%
So, the <span>color that had an experimental probability that matched its theoretical probability is blue.</span>

I'll help you darling
a. B
b. 2.6 + x = 10.4
c. x = 10.4 - 2.6
= 7.8
d. This is to say before mia added the 2.6 litres of what the pitcher contained 7.8 litres of water already

Let's solve ~
First we have to calculate g (-5) :



Now, let's find f (g (-5)) :
