Answer:
P(379<X<394) = 0.0899 = 8.99%
Step-by-step explanation:
P(379<X<394) = normalcdf(379,394,406,9) = 0.0898613146 ≅ 8.99%
Therefore, if you pick one fruit at random, the probability that it will weigh between 379 grams and 394 grams is 0.0899 or about an 8.99% chance of occurence.
X + 80 = 180
this is bc 62+18=80
how to solve
1. subtract 80 from both sides
you should be left with
x=100
<span>the sum of the first and three times the second is 54.
x + 3y = 54
3y = 54 - x
y= 54 /3 - x / 3 = 18 -x /3
</span>xy = x (18 -x /3) = 18x - x^2 / 3 = - 1/3 x ^ 2 + 18 x
<span>
</span><span>since a<0, it is concave downward, and the vertex is the maximum value. That vertex occurs at x= - b /2a = (-18) / (-2/3) = 12
</span>
<span>The first number is x=12.
The second is y = </span><span>18 -x /3 = 18- 12/ 3 = 18 - 4 = 14 </span>
Answer:
All real numbers
Step-by-step explanation:
we have
f(x) = 3x +9
The linear function has a range of all real numbers -------> (-∞, ∞)
f(x) can take any real value.
Please see attached image below, for more information
The absolute value is always either a zero or a positive number.
Therefore:
If a number is negative, then the number is less than its absolute value.
Examples to better illustrate this:
1- If a number is "0", then its absolute value is also "0" (number is equal to absolute value)
2- If a number is "25", then its absolute value is also "25" (number is equal to absolute value)
3- If a number is "-25", then its absolute value is "25" (number is less than its absolute value).
