What is 16/10 as a mixed number simplified if possible ??

ozzi

16/10 as a mixed number would be {1 6/10} or {1 3/5}. First, you figure out how many times the denominator fits into the numerator. So you see how many times ten fits into 16 (the answer would be 1) and that's your whole number. Then, you subtract the denominator from the numerator (16-10) and put our answer (5) as the numerator in the fraction next to the 1 you got in the beginning. Then, all you have to do is simplify.

EXAMPLE:

18/10
how many times does 10 go into 18? once.
1 8/10
1 4/5

Suppose that the probability a seed will germinate is 85%. What is the probability that 7 of these seeds will germinate when 10

Neporo4naja [7]

Answer: The probability that 7 of these seeds will germinate when 10 are planted is 0.1298 .

Step-by-step explanation:

Let x be the number of seeds germinate .

Since each seed is independent from other , so we can use binomial over here.

Binomial probability formula : $P(X=x)=^nC_xp^x(1-p)^{n-x}$ , where n= total trails and p is the probability of each success.

As per given : p= 0.85 , n= 10

Then, the probability that 7 of these seeds will germinate when 10 are planted will be :-

$P(X=7)=^{10}C_7(0.85)^7(1-0.85)^3\\\\=\dfrac{10!}{7!3!}(0.85)^7(0.15)^3\\\\=0.129833720754\approx0.1298$

Hence, the probability that 7 of these seeds will germinate when 10 are planted is 0.1298 .

A particular fruit's weights are normally distributed, with a mean of 446 grams and a standard deviation of 17 grams. If a fruit

LekaFEV [45]

Answer:

The weight corresponding to which weight will be larger than 14% of times equals 427.635 grams.

Step-by-step explanation:

We need to find the value of weight that corresponds to 14% of area under the normal distribution curve

It is given that

$\overline{X}=446\\\\\sigma =17$

Using standard normal distribution tables we find value of Z corresponding to 14% of the area as -1.080

Thus using the standard equation

$Z=\frac{X-\overline{X}}{\sigma }\\\\X=\sigma \times Z+\overline{X}\\\\\therefore X=427.635grams$
