(-5,-8)
The coordinates are still the same because a rotation of 360° is a complete circle, therefore the points remain in the same spot.

Can someone help me I’ve been stuck on this.
liberstina [14]

Leila will run <u>less than</u> 25 miles this week. This means the inequality symbol will be this: "<". Since she has already ran 13 miles, we need to plug-in a variable for the additional miles she must run. The inequality should be like this when plugged-in: 25 < 13 + t.

The final answer to your question is 25 < 13 + t.

0.6(10n + 25) = 10 + 5n
drek231 [11]

Answer: n=-5

Step-by-step explanation:

distribute: 0.6(10n+25)=10+5n   0.6(10n)= 6n   0.6(25)=15   so then you put the problem together again... 6n+15=10+5n then you cancel out the n variable... 10-15=-5   6n=-5+5n   6n-5n=1n   1n=-5   -5/1   n=-5

What must be true about the discriminant of this quadratic equation for the mentioned values of k? Assume p&gt;0.
Goryan [66]
<span>1/(4p)(x-h)^2+k=0

</span><span>1/(4p)(x-h)^2 = -k
</span>
<span>k(4p)(x-h)^2+1=0

4kp (x^2 - 2xh + h^2) + 1 = 0

4kp x^2 - 8kph x + 4kph^2+1 = 0

D = (-8kph)^2 - 4(4kp)(4kph^2+1) = 64(kph)^2 - 64(kph)^2 - 16kp
D = -16kp < 0

SO discriminant is always less than 0

To estimate the mean of a population with unknown distribution shape and unknown standard deviation, we take a random sample of
Naddika [18.5K]

Answer:

t_{critical} = \pm 1.7793                        

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 64

Sample mean = 22.3

Sample standard deviation = 8.8

We want to estimate 92% confidence interval.

92% Confidence interval:  

\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}  

Putting the values, we get,

Degree of freedom = n - 1 = 63

t_{critical}\text{ at degree of freedom 63 and}~\alpha_{0.01} = \pm 1.7793  

22.3 \pm 1.7793(\dfrac{8.8}{\sqrt{64}} ) = 22.3 \pm 1.95723 = (20.34,24.26)
