Answer:

p - 14.5 = 53

Step-by-step explanation:

The original price is p.

The discounted price is $14.50 less than p, or $14.50 subtracted from p. The discounted price is p - 14.5.

The discounted price is $53

Equation:

p - 14.5 = 53

The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of mon
ivanzaharov [21]

Answer:

The slope is $0.35/min and it gives the cost per minute of the phone used.

Step-by-step explanation:

We can model this situation with a linear equation of the form

y =mx+b

where y is monthly cost, x is the number of minutes, b is the flat monthly fee, and m is the slope of the equation, or in our case, the amount of money charged per minute.

The slope m is

m= \dfrac{\$372.5-\$131}{990min-300min}

m = \$0.35/min,

in other words, the phone company charges $0.5 per minute.

With the slope in hand, the linear equation becomes

y =0.35x+b,

and we can find the monthly fee b from that fact that for 300 minutes the cost is $131:

\$131 = 0.35(300min) +b

b = \%26.

Therefore,

y = 0.35x+26

where the slope if the equation give the cost per minute of the phone used.

Eight trials are simulated. The results are shown in the table.
bezimeni [28]

Answer:

2.897

Step-by-step explanation:

Let us find the mean and variance for the sample first.

105 104 110 112

114 106 108 109

Mean = sum/8 = 108.5

Variance = 12

Std dev = sq rt of variance = 3.464

Std error = std dev/ sq rt n

since n =8, we get std error = 1.225

Since sample size is small, df =8-1 =7

For 95% confidence intervals, t critical value for two tailed=2.365

Margin of error = std error x t critical = 1.225(2.365)

=2.897

When 4(0.5x+2.5y-0.7x-1.3y+4) is simplified, what is the resulting expression?
padilas [110]

Answer:

-0.8x + 4.8y + 16

Step-by-step explanation:

4(0.5x+2.5y-0.7x-1.3y+4) = 4( 0.5x - 0.7x  + 2.5y - 1.3y + 4)

= 4( -0.2x  + 1.2y + 4)

= 4*(-0.2x)  + 4 *1.2y + 4*4

= -0.8x + 4.8y + 16
