It should be something like this : y = 125 + 195x ; x = 0, 1, 2, 3, ...
Answer:
Step-by-step explanation:
b + t = 15, 2b + 3t = 45
If you need it solve:
2(b + t) = 2(15)
2b + 2t = 30 Now subtract this from the second equation
2b + 3t = 45
- 2b + 2t = 30
t = 15
There are 15 trycicles and 0 bycicles
For random samples of size 100 from a population, the mean of the sample means from all possible samples is <u>less than</u> the population means.
The suggestion of the pattern means will equal the population suggest. the standard deviation of the distribution of the sample means, called the same old blunders of the suggested, is the same as the population trendy deviation divided by means of the rectangular root of the sample length (n).
The general sample suggests components for calculating the pattern mean.
The populace suggest is the mean or average of all values within the given population and is calculated by using the sum of all values within the population denoted with the aid of the summation of X divided by way of the number of values in the population that's denoted with the aid of N.

I must assume that you meant <span>X^2-10x =7. If that is indeed the case, then:
</span>X^2-10x =7 => x^2 -10x + 25 - 25 = 7, so that (x-5)^2 = 32 (Add 25, then
subtract 25)
Then x-5 = plus or minus sqrt(16)sqrt(2) = 4sqrt(2).
Then x = 5 plus or minus 4 sqrt(2) (answers)
So 15/3 = 5 then
vinegar = 5x2 = 10 cups
water = 5x1 = 5 cups
