Roughly 1.7 percent of the bands are shorter than 3cm. We calculate the z score of the data point in standard distribution. By definition of z score, we use score minus mean divided by standard deviation. z=(3-6)/1.5=-2. A z score of -2 corresponds to approximately 1.7%, in other words, roughly 1.7 percent of data is less than 3cm.
Answer:
separate : x-4y=1
= x-2y = 10
the other one: x = 6y + 2
togetehr : x = -1 , y = -1/2
step-by-step explanation:
i don't know if they're together so ima give you the answer for them if they are and just separte answers
X²-9x+4
exponents generally go from largest to smallest, but there are other"standard" forms
Answer:
7 cm
Step-by-step explanation:
We are told that the pyramid has a square base of an area of 49 cm².
Therefore, the side length of the base of the pyramid is still the same as the side length of a square having an area of 49 cm².
Area of a square = s², where s is the side length of the square.
The side length of the base can be gotten using the following equation,
Solve for s by looking for the share root of both sides.
The side length of the base = 7 cm
Answer:
1) Write the equation of the parabola that has x-intercepts at the points (6,0) and (-2,0) is flipped vertically and is stretched by a factor of 4
