to find the volume of a sphere you must use V=4\3•π•r^3 (four thirds times pi time the radius cubed), plug in 6 into "r" in the equation and that should give you roughly 904.74

To find the volume of a pyramid you must use the equation Lwh\3 (length times width times hight product of which is divided by 3) giving you 88

If other factors are held constant, what happens to a confidence interval if the sample variance increases? The range of t score
Firlakuza [10]

Answer:

The standard error increases and the width of the interval increases

Step-by-step explanation:

The variance is equal to the square of the standard deviation. An increase in variance will increase the standard deviation.

The width of the confidence interval can be defined as:

W=UL-LL=2z\sigma/\sqrt{n}

The width is proportional to the standard deviation, so when the variance increases, the standard deviation and also the width of the interval increases.

Camden invested $1400 in an account that pays 4.5% interest compounded annually Assuming no deposits or withdrawals are made, fi
photoshop1234 [79]

The amount of money Camden would have in his account after 12 years is equal to $2,374.3.

<h3>How to calculate compound interest.</h3>

To calculate how much money Camden would have in his account after 12 years, we would use the formula for compound interest.

Mathematically, compound interest is given by this formula:

A=P(1+r)^t

<u>Where:</u>

  • A is the balance.
  • P is the principal or starting amount.
  • R is the interest rate.
  • T is the time measured in years.

<u>Given the following data:</u>

Principal = $1400.

Interest rate = 4.5% = 0.045.

Time = 12 year.

Substituting the given parameters into the formula, we have;

A=1400(1+0.045)^{12}\\\\A=1400(1.6959)

A = $2,374.3.

Estimate 58.311+49.35 by first rounding each number to the nearest whole number.
RideAnS [48]

Answer:

≈107

Step-by-step explanation:

58.311 will round <em>down </em>since 0.311 is less than half or 0.5. It will become 58. 49.35 will also round <em>down </em>since 0.35 is less than 0.5. This will be 49. 58+49=107. Since 107 is not the exact answer, you will use the approximately sign, or ≈.
