A chance with probability 1 is certain to happen true or false

KIM [24]

Probability always adds up to 1 so, if there is only one choice, the chance that it will happen is 100% (1 out of 1) so true

Hope this helps! :)

Write an expression that can be used in over a temperature from degrees Celsius see to degrees Fahrenheit and then use the expre

densk [106]

Answer:

25°C = 77 degree Fahrenheit.

Step-by-step explanation:

In this question we have to write the expression showing the relation between degree Celsius and degree Fahrenheit first.

$C=\frac{5}{9}(F-32)$ where C = degree centigrade and F = degree Fahrenheit

Although the question is not clear in the next part but assuming that we have to use this expression to convert 25°C to degree Fahrenheit,

We will plug in the value of C in the expression,

$25=\frac{5}{9}(F-32)$

$F=(\frac{9}{5}\times 25)+32$

F = 45 + 32

F = 77

Therefore, 25°C = 77 degree Fahrenheit will be the answer.

Show that (0, 0) is equidistant from (1, 2), (-1, -2) and (2, 1).

Len [333]

Step-by-step explanation:

1) if (0;0) if point A, (1;2) is point B; (-1;-2) is C, (2;1) is D, then

2) the vector AB is (1;2); vector AC is (-1;-2) and vector AD is (2;1), then

3) the length of AB, AC and AD are:

$|AB|=\sqrt{1^2+2^2}=\sqrt{5};$

$|AC|=\sqrt{(-1)^2+(-2)^2}=\sqrt{5};$

$|AD|=\sqrt{2^2+1^2}=\sqrt{5}.$

4) if the lengths above are equal, then it means that (0, 0) is equidistant from (1, 2), (-1, -2) and (2, 1).

The graph shows Kelly traveling from home to her grandmother's house: A graph is shown with the title Kelly's drive. The x-axis

Luden [163]

Answer:

<em>The correct option is: B</em>

Step-by-step explanation:

The x-axis is labeled Time driving, and the y-axis is labeled Distance driven.

Segment B is a <u>horizontal line</u> from x equals 0.5 until 1.75.

So, the value of $y$ is constant in the interval $x=0.5$ to $x=1.75$ is 0.

Thus, the distance traveled in the time interval 0.5 to 1.75 will be 0, which means the car was in the same position in that time interval.

So, the interval B on the graph indicates she is stuck in a traffic jam.
