Noel Devine bought a new dishwasher for $320. He paid 20 down and made 10 monthly payments of $34 what actual yearly interest ra
Zina [12379]
To determine the interest, we need to apply the following formula: Interest = Principal x Rate x Time or I = PRT. Substitute the values: I = [$20 + ($10 x $34)] - 320 = $40. Here, P = $320, R =?, and T = 10 months/year. Since R is the unknown, we'll find it using the formula R = I/PT. This becomes R = ($20 + ($10 x $34) - 320) / ($320 x 10 months). T = 10 months/12 months = 0.83. Thus, R = ($40)/$320 x 0.83 which simplifies to R = 40/265.6, resulting in R = 15.06024096.

There is a shop with old-style cash registers. Rather than scanning items and pulling the price from a database, the price of ea
PIT_PIT [12445]

Answer:

A list detailing the correct and incorrect prices is unavailable, making it impossible to ascertain precise answers.

Step-by-step explanation:

N.B: Without a provided list, accurate pricing cannot be guaranteed.

Manually entering barcodes or prices in an effort to determine costs can introduce mistakes in the selling price. This could adversely affect the business due to possible underpricing or overpricing.

For instance, a dress was priced at $30 incorrectly when it should have been $39. Conversely, the price of a t-shirt was accurately documented at $10. Meanwhile, the jeans were listed at $25 instead of the correct price of $23. This example illustrates two pricing errors involving clothing items: the dress is priced too low, while the jeans are priced too high.

Eva earned the following test scores in science: 82, 100, 96, 90, 91 Ms. Wade entered the next score as 0 because Eva was absent
Inessa [12570]

we know that

1) Prior to the missing test

a) mean=[82+100+96+90+91]/5=459/5------> 91.8

b) median

82,90,91,96,100-------> the median is 91


2) After introducing the 0 test score

a) mean=[82+100+96+90+91+0]/6=459/6------> 76.5

b) median

0,82,90,91,96,100-------> the median is [90+91]/2-----> 90.5


therefore

a) Following the addition of the 0 test score, utilizing the mean is the most valid measure of center for the data-------> is true


b) The inclusion of the 0 test score would influence the mean-----> is true


c) The median would be the more suitable measure of center after adding the 0 test score-----> is false


d) Eva’s median score prior to the missed test was 96-----> is false


e) Eva’s median score before the missed test was 91------ is true


f) Eva’s average score before the missed test was 91.8-----> is true

Which are the solutions of x2 = 19x + 1?
AnnZ [12381]

Answer:

(\frac{19-\sqrt{365}} {2},\frac{19+\sqrt{365}} {2})

Step-by-step explanation:

We have

x^2=19x+1

To recall, the formula for solving a quadratic equation shaped like

ax^{2} +bx+c=0

is expressed as

x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}

For this problem, we have

-x^{2}-19x-1=0  

Thus,

a=1\\b=-19\\c=-1

Substitute into the formula:

x=\frac{-(-19)\pm\sqrt{-19^{2}-4(1)(-1)}} {2(1)}

x=\frac{19\pm\sqrt{365}} {2}

x=\frac{19+\sqrt{365}} {2}

x=\frac{19-\sqrt{365}} {2}

(\frac{19-\sqrt{365}} {2},\frac{19+\sqrt{365}} {2})

Consequently, the solutions are:

StartFraction 19 minus StartRoot 365 EndRoot Over 2 EndFraction, StartFraction 19 + StartRoot 365 EndRoot Over 2 EndFraction
