Answer:
the second option : ST and WX
Step-by-step explanation:
congruent means they would completely cover each other when oriented in the same direction and positioned at the same location.
after dying the two mirroring actions we get
VS correlates to ZW
ST correlates to WX
TU correlates to XY
UV correlates to ZY
Answer:
For questions 1 the answer is 5.567 x 10^6 and for 2 the answer is 3.67 x 10^9
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
As we can observe from the answers the representation is about the pair of points. We can sort it out by excluding the wrong options.
Options B and C is incorrect because the place of x and y coordinate is given mistakenly for the point (1,2)
The option A is incorrect due to the same problem for the point (8,7)
The correct option is D.
Answer:
The variance for the number of tasters is 4.2
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they are tasters, or they are not. The probability of a person being a taster is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The variance of the binomial distribution is:
It is known that 70% of the American people are "tasters" with the rest are "non-tasters". Suppose a genetics class of size 20
This means that
So
The variance for the number of tasters is 4.2
<span> f(x)=7x+3 and g(x)=9x , what is g(x)-f(x) ?
</span>g(x)-f(x) = 9x - (<span>7x+3)
</span>g(x)-f(x) = 9x - 7x - 3
g(x)-f(x) = 2x - 3
answer is <span>2x-3 (first choice)</span>
