The table below gives the age and bone density for five randomly selected women. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting a woman's bone density based on her age. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.

Age 36 39 48 53 58
Bone Density 358 351 330 325 314
Table

Step 1 of 6 : Find the estimated slope. Round your answer to three decimal places.

Answers

Answer 1

Answer:

-1.973

Step-by-step explanation:

Given the data :

Age 36 39 48 53 58

Bone Density 358 351 330 325 314

Equation of regression line is in the form:

yˆ=b0+b1x

Where y = predicted variable ;

b0 = intercept ; b1 = slope or gradient ; x = predictor variable

Using The correlation Coefficient calculator :

The regression equation obtained is :

ŷ = -1.97316X + 427.94399

From the equation ;

The slope or gradient (b1) = - 1.97316

Hence, estimated slope to 3 decimal places is : - 1.973

0-4-9 = -13 or -4-9 = -13

Explanation:

Basically it starts at 0, then it moves to the left of the number line meaning it subtracts. It moves to the left by 4, so it is subtracting 4 from 0. Then it moves to the left again by 9, so you subtract 9 from 0-4

In the end, it is 0-4-9 or you can remove the 0 and be -4-9

jordan can jog 1/3 of a mile in 1/6 of an hour.what is his speed in miles per hour

Answers

Answer:

The answer is  2 miles per hour

Step-by-step explanation:

Given

distance = 1/3 miles

time taken = 1/6 hour

Required,

The speed with which Jorgan Jogs

Step two:

We know that the formula for the situation is

Speed= distance/time

Speed= 1/3/1/6

Speed= 1/3*6/1

multiply the numerator by the inverse of the denominator

Speed=6/3

Speed= 2 miles per hour

If the probability is 0.65 that a marriage will end in divorce within 20 years, what is the probability that out of 7 couples just married in the next 20 years
(A) None will be divorced?
(B) All will be divorced?
(C) Exactly 6 will be divorced?
(D) At least 6 will be divorced?

Answers

Answer:

0.00064

0.049

0.185

0.234

Step-by-step explanation:

Using binomial distribution formula :

P(x = x) = nCx * p^x * (1 - p)^(n-x)

p = 0.65

1 - p = 1 - 0.65 = 0.35

n = 7

(A) None will be divorced?

P(x = 0) : 7C0 * 0.65^0 * 0.35^7

= 1 * 1 * 0.00064339296875

= 0.00064

(B) All will be divorced?

P(x = 7) : 7C7 * 0.65^7 * 0.35^0

1 * 0.04902227890625 * 1

= 0.049

(C) Exactly 6 will be divorced?

P(x = 6) : 7C6 * 0.65^6 * 0.35^1

7 * 0.075418890625 * 0.35

= 0.18477628203125

= 0.185

(D) At least 6 will be divorced?

P(x ≥ 6) = p(6) + p(7)

P(6) = 0.185

P(7) = 0.049

P(x ≥ 6) = 0.185 + 0.049 = 0.234

x = -8

Step-by-step explanation:

Solve for x by getting rid of the fraction.

414 = -23(x-10)

414 = -23x + 230

184 = -23x

A plane takes off from an airport on the bearing S 29°W. It continues for 20 minutes then changes to bearing S 52°W and flies for 2 hours 20 minutes on this course then lands at a second airport. If the plane's speed is 420 mph, how far from the first airport is the second airport? Round to the nearest mile.
A. 1011 mi
B. 1111 mi
C. 1010 mi
D. 1110 mi

Answers

Answer: 1110 miles

Step-by-step explanation:

Given that :

Speed (V) = 420 mph

t1 = 20 minutes = 20/60 = 0.3333 hour

t2 = 2 hours 20 minutes = 2.333 hours

Distance = speed * time

d1 = 420 * 0.333 = 140 miles

d2 = 420 * 2.33333 = 979.98 = 980 miles

Using cosine rule :

x = sqrt(d1² + d2² - 2(d1 * d2) cos 157

x = sqrt(140^2 + 980^2 - 2(140 * 980) cos157

x = sqrt(1232586.5)

x = 1110.2191

x = 1110 miles

Answers

Answer:

Product = [tex]\dfrac{64}{135}[/tex]

Step-by-step explanation:

The expression is as follows :

[tex]\dfrac{4}{7}\times \dfrac{8}{9}\times \dfrac{14}{15}[/tex]

We need to find the product of the above expression

As 7 × 2 = 14

So, it will become :

[tex]4\times \dfrac{8}{9}\times \dfrac{2}{15}\\\\=\dfrac{4\times 8\times 2}{9\times 15}\\\\=\dfrac{64}{135}[/tex]

So, the product of the given fractions is [tex]\dfrac{64}{135}[/tex].
