Answer:

26

Step-by-step explanation:

Applying the tangent-secant theorem, we get:

12^2 = 8 * (x + 10)

144 = 8x + 80

= 8x = 144 - 80

8x = 64

x = 8

Putting x = 8 in ED, which is x + x + 10, we get:

= 8 + 8 + 10

= 26

Hope this helps!

Answer:

ED = 26

Step-by-step explanation:

Using tangent-secant theorem

(12)²=(8)(x+10)

144=8x+80

144-80=8x

8x = 64

x=8

Now

ED = 8+8+10

ED = 26

The mean monthly rent of students at Oxnard University is $780 with a standard deviation of $208.
Nonamiya [84]

Answer:

a) 2.188

b) John's rent is not an outlier

c) His rent has to be higher than $1,235 to be an outlier

Step-by-step explanation:

The mean monthly rent of students at Oxnard University is $780 with a standard deviation of $208.

(a) John’s rent is $1,235. What is his standardized z-score?

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = $1235

μ is the population mean = $780

σ is the population standard deviation = $208

Hence,

z = 1235 - 780/208

z = 2.1875

Approximately to 3 decimal place = 2.188

(b) Is John’s rent an outlier?

No it isn't

(c) How high would the rent have to be to qualify as an outlier?

John’s rent would have to be higher than $1235

A flock of 200 birds were flying south for the winter. Every day, the amount of birds in the flock increased by an average of 4%
astra-53 [7]

Answer:

b=200(1.04)^{d}

Step-by-step explanation:

we know that

The exponential function is of the form

y=a(b)^{x}

where

a is the initial value

b is the base

In this problem we have

a=200 birds

b=100%+4%=104%=104/100=1.04

substitute

y=200(1.04)^{x}

Let change of variables

b=200(1.04)^{d}

where

b is the amount of birds in the flock

d is the number of days since the 200 birds started

Shannon test-drives a car in Germany and drives 95 kilometer per hour. What is her speed in miles per hour? (1 kilometer &lt; 0.
victus00 [196]

Answer:

58.9 miles per hour

Step-by-step explanation:

Step 1: Convert 95 Kilometers per hour to miles per hour

1 Kilometer = 0.62 miles

95 Km x \frac{0.62 miles}{1 km}

cancel Km

95 Km x \frac{0.62 miles}{1 km}  = \frac{95}{1} x \frac{0.62 miles}{1} = \frac{58.9 miles}{1} or 58.9 miles

Change it into speed

58.9 miles per hour (59 miles per hour (Round off))

(Note: I don't know if I should round off because the instructions aren't that clear. This solution might or might not have been thought to you by your lecturer.)
