A helicopter is hovering above a road at an altitude of 24 m. At a certain time, the distance

LuckyWell [14K]

Answer: 32.23°

Suppose the setpoint of a helicopter is A and that of a car is C and that of the road is B

The distance from the helicopter to the car and the road forms a right triangle

=> ΔABC is a right triangle at B

=> the angle of depression from the helicopter from the car is ∠ACB

we have: ΔABC is a right triangle => sin ∠ACB = 24/45

=> m∠ACB = 32.23°

The systolic blood pressure of 18-year-old women is a roughly bell-shaped distribution with a mean of 120 mmHg and a standard de

saw5 [17]

Answer:

C. approximately 99.99%

Step-by-step explanation:

The distribution bell shape is a normal distribution, with mean 120 mmHg and standard deviation 12 mmHg.

The rank between 96 mmHg and 144 mmHg is wider than the rank between mean plus, minus 3 standard deviation (102 mmHg up to 138 mmHg), and this rank is approximately 99.7 %.Therefore 99.99 % includes more closely values in the rank 96 up to 144 mmHg

Identify an equation in slope – intercept‘s form for the line parallel to Y=5x+2 that passes through (-6,-1).

maksim [4K]

Slope-intercept form of a line is y=mx+b where m= slope and b=y-intercept.

First step is to compare this line with the given line y=5x+2 to get the value of m.

After comparing we will get m=5.

Now slope of all parallel lines are equal which means if slope of this line is 5 then slope of the line which is parallel to this line will also be 5.

Point- slope form of a line is:

$y-y_{1} =m(x-x_{1} )$

Given the line passes through (-6,-1). So, plug in x1=-6, y1=-1 and m=5 in the above equation. So,

y-(-1)=5(x-(-6))

y+1=5(x+6)

y+1=5x+30

y=5x+30-1

y=5x+29.

The larger the standard deviation is for a data set, the more variable the data in the set are. True or false?

erik [133]

True.

If the standard deviation value is larger, it means the data points are further away from the mean - which indicates that the data in the set are more variable.

In 1990, the average income for an American worker was $1,518 per month. In 2000, the average income for an American worker w

mario62 [17]

Answer:

Decreased

Step-by-step explanation:

-The rate of growth in food prices can be calculated using the compound interest formula as:

$A=P(1+i)^t\\\\1402=657(1+i)^{10}\\\\(1+i)=(\frac{1402}{657})^{0.1}\\\\1+i=1.07874\\\\i=0.07874$

We use the calculated growth rate in food prices to find the potential future value of a 90's income:

$A=P(1+i)^n\\\\=1518(1.07874)^{10}\\\\=3239.21$

#Compare this calculated value to the stated value:

$3239.21>2632$

Hence, the real value of income has decreased since it's less than it's future value over the 10-year period.
