Slope intercept form for the line with y-intercepts -1 and slope -4
baherus [9]

The slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

We know:

Slope (m) is -4

y-intercept (b) is -1

All you need to do is plug these numbers into the slope intercept formula given above!

y = -4x - 1

Hope this helped!

If 15 actuators have failed today, what is the probability that a) at least 10 are repairable? b) from 3 to 8 are repairable? c)
Ann [662]

The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.

According to the statement

we have given that If 15 actuators have failed and we have to find the probabilities on some conditions.

we know that the formula of probabilities is

probability = possible outcomes / total outcomes

So,

  • at least 10 are repairable = 1 - (10 are not repairable)

at least 10 are repairable = 1 - 10/15

at least 10 are repairable = (15 - 10)/15

at least 10 are repairable = (5)/15

at least 10 are repairable = 1/3

  • from 3 to 8 are repairable = 3/15 *8/15

from 3 to 8 are repairable = 1/5 *8/15

  • exactly 5 are repairable = 5/15

exactly 5 are repairable = 1/3

These are the probabilities of the given conditions.

So, The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.

These data show the number of miles each of the 9 members of a track team ran for the week. 11 11.5 10.5 17 14.5 14.5 18 17 19 W
Vitek1552 [10]
Given:
<span>11 11.5 10.5 17 14.5 14.5 18 17 19

Arrange in chronological order from least to greatest.
10.5 ; 11 ; 11.5 ; 14.5 ; 14.5 ; 17 ; 17 ; 18 ; 19

</span><span>I used an online lower and upper fence calculator to get the necessary data.

Minimum: 10.5
Maximum: 19
Q1: 11.25
Q2 or median: 14.5
Q3: 17.5

Interquartile range can be solved by subtracting the value of Q1 from the value of Q3

IQR = Q3 - Q1
IQR = 17.5 - 11.25
IQR =  6.25  CHOICE A. </span>

Define natural hazard?

A natural hazard is a natural phenomenon that might have a negative effect on humans and other animals, or the environment. Natural hazard events can be classified into two broad categories: geophysical and biological.

What is the difference between tectonic hazards and weather hazards ?

Tectonic hazards occur when the Earth's crust moves. For example, when the plates move, friction can cause them to become stuck. Tension builds until the plates release, which leads to an earthquake. Climatic hazards occur when a region has certain weather conditions, for example heavy rainfall can lead to flooding.

why do convection currents in the mantle occur?

Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart
