Answer:

No, water is not a liquid if its temperature is above 100° C or below 0°C.

water below 100° C would be convert in to gas and Below the 0° C water would be solid.

Step-by-step explanation:

Given : Graph line.

To find : water is not a liquid if its temperature is above 100° C or below 0°C

Explanation : We have given two temperature 100° C and 0 ° C.

For 100° C :

Boiling point of water : The temperature at which water start boiling .

That is 100° C.

So, water below 100° C would be convert in to gas.

Freezing point : The temperature at which water start freezing .

That is 0° C.

So, Below the 0° C water would be solid.

Therefore, No, water is not a liquid if its temperature is above 100° C or below 0°C.

water below 100° C would be convert in to gas and Below the 0° C water would be solid.

Given the equation y=14x2−5, the minimum is ___ and the range is ___

mel-nik [20]

Answer:

The minimum is -5

The range is $y \ge -5$

f(14) = 2739

Step-by-step explanation:

Given

$y = 14x^2 - 5$

Solving (a): The minimum

A quadratic function is represented as:

$y = ax^2 + bx + c$

If a > 0, then the function has a minimum

By comparison

$a = 14$ --- the function has a minimum

$b = 0$

$c = -5$

To calculate the minimum, we first calculate the following is calculated as:

$m = -\frac{b}{2a}$

So, we have:

$m = -\frac{0}{2*14}$

$m = 0$

So, the minimum is at f(m)

We have: $y = 14x^2 - 5$

$f(0) = 14 *0^2 - 5$

$f(0) = - 5$

Solving (b): The range

In (a), we have:

$f(0) = - 5$ --- the minimum

This implies that the smallest value of y on the graph is -5.

So, the range is:

$r = \{y|y\ge -5\}$

Solving (c): f(14)

We have:

$y = 14x^2 - 5$

So:

$f(14) = 14 * 14^2 - 5$

$f(14) = 2739$

While bowling, Sarah made 5 strikes out of her last 18 frames. David made 9 strikes out his last 25 frames. What is the probabil

Alla [95]

Answer:

1/10 or 0.1

Step-by-step explanation:

Probability of occurrence of any event = number of favorable event by total /number of occurrence of event.

For Sarah

Given Number of frames = 18

Number of strikes made by her = 5

Therefore by using the above formula to get the probability of striking by Sarah will be 5/18.

__________________________________________________

For David

Given Number of frames = 25

Number of strikes made by him = 9

Therefore by using the above formula to get the probability of striking by David will be 9/25.

__________________________________________________

Since the event of Sarah and David are mutually independent i.e occurrence of one event does not impact the occurrence of other event.

Probability of occurrence of two mutually independent A and B event with Probability P(A) and Probability P(B) is given by P(A) * P(B).

Therefore probability that they both get a strike on their next frame are mutually independent event with probability 5/18 and 9/25 will be calculated by 5/18 * 9/25 = 1/(2*5) = 1/10.
