rs. During the second half of the race, he walked for 2 miles and ran at a rate of 5.5 miles per hour for x hours. What equation could you write to solve for the number of hours Ben ran during each half of the race? Let y represent the number of miles in half the race. Write two equations, one for the first half of the race and one for the second half. How could you transform these two equations to be the same as the original equation you wrote to solve for x? What do you think this means about solving for the variables in a situation represented by two equations?

Response:

y = 5x + 3

y = 5.5x + 2

0.5x = 1

x = 2

y = 13

In any case, I believe this indicates that x in the second equation corresponds to x, and y in the second equation corresponds to y

How much would it cost to buy 100 shares in ODX group Inc and 300 shares
PIT_PIT [12445]

Complete Question

The entire question can be found in the first uploaded image

Answer:

The expense for acquiring 100 shares of ODX group Inc and 300 shares of peer Comms Lts is

         C  =  \$ 775

Step-by-step explanation:

   From the chat, the expense for 100 shares of ODX is \$175

    The price of 100 shares of peer Comms Lts is \$ 200

Thus, the cost for 300 shares of peer Comms Lts amounts to k  =  3 * 200 =  \$ 600

Overall, the total cost for 100 shares of ODX group Inc and 300 shares of peer Comms Lts can be calculated as

           C  =  175 + 600

           C  =  \$ 775

Tesla wanted to determine the average miles per kWh that their vehicles get across all models and variations. They took a sample
lawyer [12517]

Answer:

\mu_{\bar x} = \mu = E(X) =30KWh

\sigma_{\bar X}= \frac{\sigma}{\sqrt{n}}=\frac{3}{\sqrt{100}}=0.3

Step-by-step explanation:

Previous concepts

Normal distribution, is defined as a symmetric "probability distribution centered around the mean, indicating that values near the mean are more common than those further away".

The Z-score measures a value's relation to the mean of a set of values, displayed in terms of how many standard deviations away it is from that mean.

According to the central limit theorem, "with a population having mean μ and standard deviation σ, if we draw sufficient random samples from this population with replacement, the means of those samples will resemble a normal distribution, regardless of the original population's shape, as long as the sample size is large enough".

Solution to the problem

In this scenario, we select a sample size of n = 100

The central limit theorem informs us that the distribution of the sample mean \bar X is defined by:

\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})

Thus, the mean for the sample would be:

\mu_{\bar x} = \mu = E(X) =30KWh

And the standard deviation would be:

\sigma_{\bar X}= \frac{\sigma}{\sqrt{n}}=\frac{3}{\sqrt{100}}=0.3

Zina [12379]
La opción correcta es D. tarjeta 4. Explicación paso a paso: Observa el gráfico proporcionado. El APR introductorio es una tasa de interés reducida que las compañías de tarjetas de crédito suelen ofrecer a nuevos clientes durante un número determinado de meses. La mayoría de las tarjetas de crédito brindan APRs descontados en pagos, transferencias de saldo o en ambos. El gráfico de la tarjeta 4 muestra que la tasa de interés entre enero y abril fue menor, y después de abril, la tasa de interés aumentó con una pendiente diferente. Por lo tanto, la opción correcta es D. tarjeta 4.
