Helga [31]4 years ago

Answer:

∠2 and ∠3 are complementary

Step-by-step explanation:

Complementary angles add up to 90°. Angles 1 and 3 are complementary, so the formula is ∠1 + ∠3 = 90°. Given that Angle 1 equals to angle 2, we substitute angle 2 for angle one in the equation stated before. Now we have ∠2 + ∠3 = 90°, so angles 2 and 3 are complementary

A​ city's mean minimum daily temperature in February is 22 degrees Upper F. Suppose the standard deviation of the minimum temper
Misha Larkins [42]

Answer:

Probability that X <32 degrees

=P(Z

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

=P(Z

Convert this into percent by multiplying by 100

95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )​

The variables x and y vary directly. Use the values to find the constant of proportionality and write an equation that relates x
Leya [2.2K]

Answer:

y = 4x

Step-by-step explanation:

If y is directly proportional to x (which is what I assume you are meaning in this question), this means that

y = kx, where k is the constant of proportionality.

To find k, we simply substitute in the given x and y values, and solve for k. i.e we to get:

8 = k x 2.

k = 8/2 = 4.  

so y = 4x

(For this equation any non-integer values should be entered as fractions)
bazaltina [42]
<span> y = 2/7 x - 1/7
slope = 2/7
</span><span>perpendicular  lines, slope is opposite and reciprocal
</span>so slope of new line = -7/2
<span>passes through the point (9,-32)
</span><span>slope-intercept form: y = mx + b
so
b = y - mx
b = -32 - (-7/2)(9)
b = -32 + 63/2
b = -1/2

equation in </span>slope-intercept form:
y = -7/2 x - 1/2
