Answer:

Usually in the equation they use Sin, Cos, or tan. Although, If the point in the graph starts at 0 is is sin and anything else would be cos. Tan is the sort of vertical squiggly line.

jeka57 [31]

1.)

7 \frac{3}{9}  - 2 \frac{4}{9}  \\  =  \frac{66}{9}  -  \frac{22}{9}  \\  =  \frac{44}{9}  \\  = 4 \frac{8}{9}

2.)

11 \frac{3}{4}  - 5 \frac{1}{4}  \\  =  \frac{47}{4}  -  \frac{21}{4}  \\  =  \frac{26}{4}  \\  =  \frac{13}{2}  \\  = 6 \frac{1}{2}

Answer:

a: 28 < µ < 34

Step-by-step explanation:

We need the mean, var, and standard deviation for the data set.  See first attached photo for calculations for these...

We get a mean of 222/7 = 31.7143

and a sample standard deviation of: 4.3079

We can now construct our confidence interval.  See the second attached photo for the construction steps.

They want a 90% confidence interval.  Our sample size is 7, so since n < 30, we will use a t-score.  Look up the value under the 10% area in 2 tails column, and degree of freedom is 6 (degree of freedom is always 1 less than sample size for confidence intervals when n < 30)

The t-value is: 1.943

We rounded down to the nearest person in the interval because we don't want to over estimate.  It said 28.55, so more than 28 but not quite 29, so if we use 29 as the lower limit, we could over estimate.  It's better to use 28 and underestimate a little when considering customer flow.

what is the area of the figure ? answers a. 12 units2 b. 17 units 2 c. 16 units 2 d. 24 units2 e. none
stellarik [79]

Answer:

  17 square units

Step-by-step explanation:

There are several ways you can divide this figure into areas that are easily computed.

One that comes to mind is to consider the triangle that would include the missing area at lower right. That triangle would have a base of 6 and a height of 8, so an area of ...

  A = (1/2)bh

  A = (1/2)(6)(8) = 24 . . . . square units

The part at lower right that is cut out is a sort of reversed L-shape that is 3 squares along the bottom and 4 more up the side, for a total of 7 squares.

Then the area of the shaded part is ...

  A = 24 - 7 = 17 . . . . square units
