Answer:
Probability that X <32 degrees

Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )
Step-by-step explanation:
Given that a city's mean minimum daily temperature in February is 22 degrees Upper F, with std deviation 6 degrees.
Let X be the minimum temperature in February
Then X is N(22,6)
To calculate percentage of days in February has minimum temperatures below freezing (32 degrees Upper F )
Probability that X <32 degrees

Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )

Answer:
(a). Function 1
(b) Function 2
(c) Function 1,2 and 4
Step-by-step explanation:
Find the equation for all functions;
function 1: y= 2x+1
function 2: y= -2x+3
function 3: y= 5x-2
function 4: y= -4x-4
for answer of (a) y= mx+c
c is intercept. so function 1 has closest intercept to 0
for (b) the greatest y intercept is function 2
for(c) slope is m: we have function 1, 2 and 4
Answer:
x = 56.7
Step-by-step explanation:
cos theta = adjacent/hypotenuse
cos x = 17/31
x = arccos(17/31)
x = 56.7
The answer is tens because all the numbers the decimal end with an ‘s’, and all the numbers the decimal end with a ‘ths’.
