Answer:

Slope intercept form of the line is y = $\frac{9}{10}x-\frac{9}{10}$

Step-by-step explanation:

Equation of a line has been given as -9x + 10y = -9

It's a standard form of the equation and we have to convert it into slope intercept form.

Slope intercept form of the line is in the form of y = mx + c

Where m = slope of the line

c = y-intercept of the line

-9x + 10y = -9

10y = 9x - 9

y = $\frac{1}{10}(9x-9)$

y = $\frac{9}{10}x-\frac{9}{10}$

Therefore, slope intercept form of the line will be y = $\frac{9}{10}x-\frac{9}{10}$

Slope intercept form is y = mx + b

so make the equation look like that.

-9x + 10y = -9 ... add 9x on both sides
10y = -9 + 9x
10y = 9x - 9

y = (9/10)x - (9/10)

A mattress store sold 1,330 mattresses in one year. If 30% of the mattresses sold were king size mattresses, how many king size

kodGreya [7K]

The total number of mattresses that are sold in a year = 1,330

Percentage of King size mattresses sold = 30% = 30/100 = 0.3

Next, we have to calculate the actual number sold by using the formula given below:

Number of king size mattresses sold = Total mattresses sold in a year * percentage of king size mattresses sold

Number of King Size mattresses sold = 1,330*0.3 = 399

Number of king size mattresses sold = 399

A sports statistician was interested in the relationship between game attendance (in thousands) and the number of

Luda [366]

Answer:

The predicted number of wins for a team that has an attendance of 2,100 is 25.49.

Step-by-step explanation:

The regression equation for the relationship between game attendance (in thousands) and the number of wins for baseball teams is as follows:

$\hat y = 4.9\cdot x + 15.2$

Here,

y = number of wins

x = attendance (in thousands)

Compute the number of wins for a team that has an attendance of 2,100 as follows:

$\hat y = 4.9\cdot x + 15.2$

$=(4.9\times 2.1)+15.2\\=10.29+15.2\\=25.49$

Thus, the predicted number of wins for a team that has an attendance of 2,100 is 25.49.

ACME Manufacturing claims that its cell phone batteries last more than 32 hours on average in a certain type of cell phone. Test

son4ous [18]

Answer:

We can conclude that the battery life is greater than the 32 hour claim.

Step-by-step explanation:

The null hypothesis is:

$H_{0} = 32$

The alternate hypotesis is:

$H_{1} > 32$

Our test statistic is:

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}$

In which X is the statistic, $\mu$ is the mean, $\sigma$ is the standard deviation and n is the size of the sample.

In this problem, we have that:

$X = 37.8, \mu = 32, \sigma = 10, n = 18$

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$t = \frac{37.8 - 32}{\frac{10}{\sqrt{18}}}$

$t = 2.46$

We need to find the probability of finding a mean time greater than 37.8. If it is 5% of smaller(alpha = 0.05.), we can conclude that the battery life is greater than the 32 hour claim.

Probability of finding a mean time greater than 37.8

1 subtracted by the pvalue of z = t = 2.46.

z = 2.46 has a pvalue of 0.9931

1 - 0.9931 = 0.0069 < 0.05

So we can conclude that the battery life is greater than the 32 hour claim.
