What is the value of z?

Mathematics
1 answer:
zlopas [31]2 years ago
3 0

Answer:

Step-by-step explanation:

The value of the z-score tells you how many standard deviations you are away from the mean. ... A positive z-score indicates the raw score is higher than the mean average. For example, if a z-score is equal to +1, it is 1 standard deviation above the mean. A negative z-score reveals the raw score is below the mean average

Which of the following best describes interval C on the graph shown?
olya-2409 [2.1K]

Answer:

Linear decreasing

Step-by-step explanation:

we know that

In the interval A we have a linear increasing function, because is a line and the slope is positive (as the value of x increases the value of y increases and as the value of x decreases the value of y decreases)

In the interval B we have a linear constant (the value of y is the same for all values of x)

In the interval C we have a linear decreasing function, because is a line and the slope is negative (as the value of x increases the value of y decreases and as the value of x decreases the value of y increases)

In the interval D we have a linear increasing function, because is a line and the slope is positive (as the value of x increases the value of y increases and as the value of x decreases the value of y decreases)

therefore

Interval C is a linear decreasing

Dean loves rocks! He has 666 pieces of granite, 333 pieces of marble, 141414 pieces of sandstone, and 111 pieces of slate.
uranmaximum [27]

Answer:

The ratio of sanstone to marble is... 141414 : 333

All you have to do is look at how much sandstone Dean has and how much marble he has, then put the amount of sandstone infront of the amount of marble because in the question it says what is the ratio of sandstone to marble and you see that sandstone is first.

Hope this helps! :)
