Answer:

3rd

Step-by-step explanation:

Negative suggests that whatver the graph is, it's the opposite of the original function. That leaves us with 2 and 3 (since 1st one is positive x^3 )

Now, the degree 3 tells you that it has to be number3 because that's the 3rd degree graph, Since second one is a upside down parabola which means -x^2

Hope this cleared things up for you!

Answer:

$\displaystyle Third\:graph$

Step-by-step explanation:

All you have to do is pick the graph that comes down from the left to the right because the cubic function is negative. This would be a the third graph.

Solve the equation (5×+7)1/5=(8-6×)1/5

AURORKA [14]

(5x+7)(1/5)=(8−6x)(1/5)
Simplify both sides. In order to do this you need to distribute 1/5 in each expression.
(5x)(1/5)+(7)(1/5)=(8)(1/5)+(−6x)(1/5)
x+7/5=8/5+−6/5x
x+7/5=−6/5x+8/5
Now you need to add (-6/5)x to both sides. This leaves you with
(5/11)x+7/5=8/5
Now subtract 7/5 from both sides.
(5/11)x=1/5
Divide both sides by 5/11
x=1/11

A set average city temperatures in August are normally distributed with a mean of 21.25 degrees Celsius and a standard deviation

Ainat [17]

Answer:

The proportion of temperatures that lie within the given limits are 10.24%

Step-by-step explanation:

Solution:-

- Let X be a random variable that denotes the average city temperatures in the month of August.

- The random variable X is normally distributed with parameters:

mean ( u ) = 21.25

standard deviation ( σ ) = 2

- Express the distribution of X:

X ~ Norm ( u , σ^2 )

X ~ Norm ( 21.25 , 2^2 )

- We are to evaluate the proportion of set of temperatures in the month of august that lies between 23.71 degrees Celsius and 26.17 degrees Celsius :

P ( 23.71 < X < 26.17 )

- We will standardize our limits i.e compute the Z-score values:

P ( (x1 - u) / σ < Z < (x2 - u) / σ )

P ( (23.71 - 21.25) / 2 < Z < (26.17 - 21.25) / 2 )

P ( 1.23 < Z < 2.46 ).

- Now use the standard normal distribution tables:

P ( 1.23 < Z < 2.46 ) = 0.1024

- The proportion of temperatures that lie within the given limits are 10.24%

A bowl of soup at 95!C (too hot) is placed in a 22!C room. One minute later, the soup has cooled to 83!C. When will the temperat

worty [1.4K]

Answer:

in 3 minutes and 50 seconds

Step-by-step explanation:

soup = 95c

after 1 minute = 83c

after 2 minutes = 71c

after 3 minutes = 59

soup cools down 0.2c in 1 seconds

so 10 seconds = 2c

in 3 minutes and 50 seconds = 49c
