Answer:

1/7.

Step-by-step explanation:

To solve this, we can simply use an equation to solve for the slope using two points:

$m= \frac{y_{2}-y_{1} }{x_{2}-x_{1}}$ We can substitute our points giving us:

$m= \frac{1-0}{7-0}$ $= m= \frac{1}{7}$

The slope of the graph is 1/7!

Answer:

a) Expected value of the mean = 0.793 percent

b) Standard error = 0.019 percent.

Step-by-step explanation:

Given

mean = μ = 0.793 percent

Standard deviation = σ = 0.114 percent

a) The sample mean is related to the population mean through

μₓ = μ = 0.793 percent

Hence, the expected value of the sample mean = 0.793 percent.

b) The standard error is given as

Standard error = σ/√n

where n = sample size = 36

Standard error = (0.114/√36)

Standard Error = 0.019 percent.

Hope this Helps!!!

Find the slope of the line that passes through (10, 9) and (3, 18).

MakcuM [25]

Answer: Slope of the line is -9/7

Step-by-step explanation:

Given :

Points : (10,9) and (3,18)

Now slope of line when two points are given

m= $\frac{y2-y1}{x2-x1}$

Slope = $\frac{18-9}{3-10}$

m= $\frac{9}{-7}$

m= $\frac{-9}{7}$

This is an improper fraction since numerator is greater than the denominator

Hence slope of the line is -9/7

A woman plans to buy some bottles of alcohol, a bottle of Heineken goes for $800 while that of monster drink $250. she doesn't h

Alja [10]

Answer:

The inequalities that must be satisfied is

$x + y \leq 32$

$x(800) + y(250) \leq 3500$

Step-by-step explanation:

Let the number of Heineken bottles be x

Let the number of monster drink bottles be y

Her crate cannot hold more than 32, This situation can be represented as

$\text{Number of Heineken bottles + number of monster drink bottles } \leq 32$

That is

$x + y \leq 32$ ------------------------(1)

Cost of one Heineken bottles = $800

Cost of one monster drink bottles = $250

then

$x \times \text{cost of one Heineken bottle } + y \times \text{ cost of one monster drink bottle} \leq 3500$ x

$x(800) + y(250) \leq 3500$ ------------------(2)

Apr 24,8:28:53 AM<br> Find the 98th term of the arithmetic sequence -10,-8, -6, ...

Nata [24]

Answer: 184

Step-by-step explanation:

The nth term of am arithmetic sequence is calculated as:

Nth term= a+(n-1)d

where a = first term

d = common difference

a = -10

d = -8 -(-10) = -8+10 = 2

98th term= a+(n-1)d

= -10 + (98-1)(2)

= -10 + (97×2)

= -10 + 194

= 184

The 98th term of the arithmetic sequence is 184
