Answer:

1:20 PM

Answer:

1:10 AM

Step-by-step explanation:

The 4th eruption of the day as at 12:22 PM. And since the time between each eruption gets 12 minutes added, the next eruption is going to happen in 48 minutes, which is at 1:10 AM. After that eruption, the time will reset and the next eruption will happen at 1:22 AM

kari74 [83]

Measuring the height of a tree is usually more difficult than measuring the diameter of the tree, confidence interval for the slope is mathematically given as

C=(0.396, 1.712)

<h3>What is a 95 percent confidence interval for the slope of the population regression line?</h3>

Generally, the equation for the confidence interval  is mathematically given as

C=\beta-tn-2, \alpha /2 (S.E)

Where

\beta=1.054

Therefore

C=(1.054-t29, 0.025*0.322)

C=(0.396, 1.712)

In conclusion, the  95 percent confidence interval is

C=(0.396, 1.712)

Work out and explain angle size - i will mark you as brainliest
postnew [5]

∠AXY=∠XBC=55°(corresponding angles)

XB=XC⇒ΔXBC is isosceles, so ∠XBC=∠XCB=55°

The sum of all the angles in a triangle is 180°⇒

55°+55°+∠BXC=180°

∠BXC=70°

NEED HELP ASAP PLEASE WILL MARK BRANLIEST What would the equation of a hyperbola with directrices at x=±2 and foci at (6,0) (-6,
andriy [413]

Answer:

The equation of the hyperbola can be presented as follows;

\dfrac{\left x   \right ^{2}}{12} - \dfrac{\left y   \right ^{2}}{24} = 1

Step-by-step explanation:

We have the equation of an hyperbola given as follows;

\dfrac{\left (x - h  \right )^{2}}{a^{2}} - \dfrac{\left (y - k  \right )^{2}}{b^{2}} = 1

The foal length = a² + b² = c²

c = focal length

The directrix = a²/c

The focal point are (h + c, k) and (h - c, k)

Therefore, by comparison with the given focal points, (6, 0) and (-6, 0), we have;

k = 0 and h + c = 6, h - c = -6

Therefore;

6 - c - c = -6

-2·c = -12

c = 6

h = 0

a²/c = 2

a² = 2 × 6 = 12

a = 2·√3

12 + b² = 6²

b² = 6² - 12 = 24

b² = 24

b = 2·√6

The equation of the hyper bola can then be written as follows;

\dfrac{\left (x - 0  \right )^{2}}{12} - \dfrac{\left (y - 0  \right )^{2}}{24} = 1

Which gives

\dfrac{\left x   \right ^{2}}{12} - \dfrac{\left y   \right ^{2}}{24} = 1

x² - y² = 12

y² = x² - 12.
