A car weighs 3.6 tons. Find its weight in pounds.

Olivia bought some granola bars and spent at least $6.24. Write and solve an equality to find the number of granola bars she bou

marishachu [46]

Answer:

n ≥ 6.24/x

Step-by-step explanation:

Given that :

Amount spent is atleast $6.24

Let price spent = p

p ≥ $6.24

If cost of granola bar = x

The number of granola bars, n purchased will be :

n ≥ 6.24/x

Since cost of granola bar isn't given, we represent it as x.

A sample of 8 buttons is randomly selected and the following diameters are measured in inches. Give a point estimate for the pop

kenny6666 [7]

Answer:

$\bar X= \frac{1.83+1.85+1.79+1.73+1.69+1.74+1.76+1.70}{8}= 1.76125$

Now we can estimate the population variance with the sample variance given by:

$s^2 = \frac{\sum_{i=1}^n (x_i -\bar X)^2}{n-1}$

And replacing we got:

$s^2 = 0.0033839$

And the estimator for the population deviation $\sigma$ is given by :

$\hat \sigma = \sqrt{s^2}= \sqrt{0.0033839}= 0.058172$

Step-by-step explanation:

For this case we have the following data given:

1.83,1.85,1.79,1.73,1.69,1.74,1.76,1.70

First we need to calculate the mean with the following formula:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X= \frac{1.83+1.85+1.79+1.73+1.69+1.74+1.76+1.70}{8}= 1.76125$

Now we can estimate the population variance with the sample variance given by:

$s^2 = \frac{\sum_{i=1}^n (x_i -\bar X)^2}{n-1}$

And replacing we got:

$s^2 = 0.0033839$

And the estimator for the population deviation $\sigma$ is given by :

$\hat \sigma = \sqrt{s^2}= \sqrt{0.0033839}= 0.058172$

Rebeca spent $32.55 for a photo album and three identical candles. The photo album cost $17.50 and the sales tax was $1.55. How

Marina86 [1]

Answer: $4.50 per candle

Step-by-step explanation:

$32.55 - $17.50 - $1.55 = $13.50 for all the candles

To find the price of a single candle we divide our answer by 3

13.50/3 = $4.50

Se sabe que el septimo termino de una progresion geometrica es 3 ya la razon es 1/2. Se desea saber cual es el valor del primer

AfilCa [17]

Respuesta:

192

Explicación paso a paso:

aₙ = a₁*rⁿ⁻¹

Hallando termino 1

a₇ = 3

r = 1/2

a₁ = ?

a₁ = aₙ / rⁿ⁻¹

a₁ = 3 / (1/2)⁷⁻¹

a₁ = 192
