Stella will have $160 saved after 6 months .

This is because, each month, Stella sets aside double the amount


Month 1 : $5

Month 2 : $10

Month 3 : $20

Month 4 : $40

Month 5 : $80

Month 6 : $160


Hope this is correct!

What is the approximate distance from one corner of the soccer field to the opposite corner?
mario62 [17]

Answer:

117 yards

Step-by-step explanation:

From the diagram here, we can see that we are to calculate the diagonal of the rectangular football field

we can calculate this by the use of Pythagoras’ theorem which posits that the square of the hypotenuse = the sum of the squares of the two other sides

From the diagram, the diagonal is the hypotenuse while the other two sides complete the right triangle

let’s say the diagonal is length d

Mathematically;

d^2 = 100^2 + 60^2

d^2 = 10,000 + 3,600

d^2 = 13,600

d = √13,600

d = 116.62 yards which is approximately 117 yards

) How many degrees of freedom are available for hypothesis tests and confidence intervals for single regression coefficient
sladkih [1.3K]

Answer:

We use students' t distribution therefore degrees of freedom is v= n-2

Step-by-step explanation:

<u>Confidence Interval Estimate of Population Regression Co efficient β.</u>

To construct the confidence interval for β, the population regression co efficient , we use b, the sample estimate of β. The sampling distribution of b is normally distributed with mean β and a standard deviation σ.y.x / √(x-x`)². That is the variable z = b - β/σ.y.x / √(x-x`)² is a standard normal variable. But σ.y.x  is not known so we use S.y.x and also student's t distribution rather than normal distribution.

t= b - β/S.y.x / √(x-x`)² = b - β/Sb    [Sb = S.y.x / √(x-x`)²]

with v= n-2 degrees of freedom.

Consequently

P [ - t α/2<  b - β/Sb  < t α/2] = 1- α

or

P [ b- t α/2 Sb<   β  < b+ t α/2 Sb] = 1- α

Hence a 100( 1-α) percent confidence for β the population regression coefficient for a particular sample size n <30  is given by

b± t α/2 Sb

Using the same statistic a confidence interval for α can be constructed in the same way for  β  replacing  a with b and Sa with Sb.

a± t α/2 Sa

Using the t statistic  we may construct the confidence interval for U.y.x for the given value X0 in the same manner

Y~0 ± t α/2(n-2) SY~

Y~0= a+b X0

Brainly a geometry teacher asked saul to define "obtuse triangle." saul said that an obtuse triangle is a triangle with one inte
worty [1.4K]
This is true. In order to get an obtuse triangle, one angle must be greater than 90 degrees because the definition of an obtuse triangle is an angle measuring greater than the right angle. The other angles must be less than 90 degrees because the sum of the angles must be 180 degrees.
