Answer:
T-shirt costs £10
Hat costs £3
Step-by-step explanation:
£93-£43=£50
9-4=5
£50/5=10
1 t-shirt=£10
£10x9=£90
£93-£90=£3
T-shirt = £10
Hat= £3
Answer:
The answer to your question is below
Step-by-step explanation:
2 3
Vertex (-4, -9) (-0.5, -3)
Max/min value Min of -9 Min of -3
Axis of symmetry x = -4 -0.5
Zeros -1 and -7 -3 and 2
Direction up up
y-intercept 6 -3
4 5 6
Vertex (-1, -2) (0, 0) (2, 1)
Max/min value Max = -2 Min = 0 Min = 1
Axis of symmetry x = -1 x = 0 x = 2
Zeros None 0 None
Direction down up up
y-intercept -4 0 3
Answer:
Outcome
Step-by-step explanation:
I'm not exactly certain but I believe the answer is outcome. For example: Each time the laser hits an object, the player gets a point. Because you're giving the cause, the laser hitting the object, and the effect, the player getting a point;its safe to assume that the element is outcome.
Answer:
The data item is ![X = 580](https://tex.z-dn.net/?f=X%20%3D%20580)
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score of a measure X is given by:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 400 and a standard deviation of 60.
This means that ![\mu = 400, \sigma = 60](https://tex.z-dn.net/?f=%5Cmu%20%3D%20400%2C%20%5Csigma%20%3D%2060)
z=3
We have to find X when Z = 3. So
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![3 = \frac{X - 400}{60}](https://tex.z-dn.net/?f=3%20%3D%20%5Cfrac%7BX%20-%20400%7D%7B60%7D)
![X - 400 = 3*60](https://tex.z-dn.net/?f=X%20-%20400%20%3D%203%2A60)
![X = 580](https://tex.z-dn.net/?f=X%20%3D%20580)
The data item is ![X = 580](https://tex.z-dn.net/?f=X%20%3D%20580)
