Step-by-step explanation:

Part A: Linear Equation.

  • One of the points is (0,15). This means 0,15 is the y intercept so b=15.

We can find the slope

\frac{5 - 15}{1  - 0 }  =  \frac{ - 10}{1}  =  - 10

So our equation is

y =  - 10x + 15

Part B: Exponential Equation

We know that

15 = a \times b {}^{0}

B to the zero power is 1 so

15 = a

This means a =15. Now let find b.

5 = 15 \times b {}^{1}

\frac{1}{3}  = b

So the equation is

y = 15( \frac{1}{3} ) {}^{x}

Find BC please in the picture
tatiyna

B. 25 Km. The measure of BC is 25 km.

The easiest way to solve this problem is using the cosine theorem c = √a²+b²-2ab*cos A.

BC = √AC²+AB²-2(AC)(AB)*cos A

BC = √(21km)²+(14km)²-2(21km)(14km)*cos 89°

BC = √441km²+196km²-588km²*(0.017)

BC =√637km²-10.26km²

BC = √636.74km²

BC = 25.03km ≅ 25

The original pulse rates are measure with units of​ "beats per​ minute". what are the units of the corresponding z​ scores? choo
posledela
the complete question is

 Pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute. The original pulse rates are measure with units of "beats per minute". What are the units of the corresponding z scores? Choose the correct choice below.

A. The z scores are measured with units of "beats per minute."

B. The z scores are measured with units of "minutes per beat."

C. The z scores are measured with units of "beats."

D. The z scores are numbers without units of measurement.

we know that

A z-score is the number of standard deviations from the mean a data point is. But more technically it’s a measure of how many standard deviations below or above the population mean a raw score is

The z scores are numbers without units of measurement

therefore

the answer is the option D
