mars1129 [50]2 years ago
3 0

Answer:

35 units

Step-by-step explanation:

Using Pythagoras Thereoem:

a² + b² = c²

21² + 28² = c²

c = √21² + 28² = √441 + 784 = √1,225 = 35 units

a 90% confidence interva is constructed for the population mean. If a 95% confidence interval had been constructed instead (ever
zhuklara [117]

Answer: increased

Step-by-step explanation:

  • An x% confidence interval indicates that a person can be x% confident that true population parameter lies in it.

More level of confidence more width of the interval.

As level of Confidence interval increases width of interval increases.

Width of interval \propto  level of Confidence interval

So, If a 95% confidence interval had been constructed instead of 90% the width of the interval would have been<u> increased.</u>

Help please! (no one was answering it in physics and i really need help)
aivan3 [116]

Let v_0 be the cat's speed just as it leaves the edge of the table. Then taking the point 1.3 m below the edge of the table to be the origin, the cat's horizontal position at time t is given by

x(t)=v_0t

and its height is

y(t)=1.3\,\mathrm m-gt^2

where g is 9.8 m/s^2, the magnitude of the acceleration due to gravity.

The time it takes for the cat to hit the ground is t with

0=1.3\,\mathrm m-gt^2\implies t=\sqrt{\dfrac{1.3\,\rm m}g}\approx0.36\,\mathrm s

(Unfortunately, this doesn't match any of the given options...)

The cat lands 0.75 m away (horizontally) from the edge of the table, so that its speed v_0 was

0.75\,\mathrm m=v_0(0.36\,\mathrm s)\implies v_0\approx2.08\dfrac{\rm m}{\rm s}

(Again, not one of the answer choices...)

I'm guessing there's either a typo in the question or answers.

X to the power of 2 subtract 3x for x=4
Helen [10]
First, X^2 while x is 4 =4^2, which is 4x4, which is 16 
3X while x is 4 is 12. 16-12=4. So the answer is 4
