Answer: x^ + 10x + 24
Step-by-step explanation:
The blue box is x times x which is x to the second power
the purple box is x times 4 = 4x
the green box is x times 6 = 6x
the orange box is 6 times 4 = 24
add them all up to get x^ + 10x + 24
train tickets costs: $130 (t)
Bus ticket cost: ? (b)
the bus ticket cost $26
Convert to an equation y in terms of x:
Y = (-2.4x + 48)/1.6
X Intercept is where y = 0
0 = -2.4x/1.6 + 48/1.6
X = 20
Y intercept is where x = 0
Y = (-2.4*0)/1.6 + 48/1.6
Y = 30
X and y are how coats and pants are made respectfully so the x intercept is where y = 0, meaning no pants are made, only jackets. The y intercept is the opposite, it’s how many pants can be made if no jackets are made.
you can use the formula for sample means:
[/tex]
where m stands for a value of the sample mean.
We are looking for the value, specifically for its two borderline values: 70 and 80
and their cumulative probabilities, p(z(80)) and p(z(70)). The difference p(z(80))-p(z(70))
will give the probability that m falls in the interval [70,80]
So let's get cracking at it:
These are very large values of z. You may notice that any z-table online won't even bother covering range that high - the probabilities for these values are virtually 0 (in the neg case) 1 (in the pos case).
This means that numerically the probability of the sample mean of 64 samples falling within the range of 1 standard deviation is very close to 1
So the answer choice should be 1.0
No because one has four right angles while the other has one
