Target sells a pack of iTunes gift cards for $40. Sam's Club sells them for $38.88. What is the percent decrease from Target's p

patriot [66]

We have been given that target sells a pack of iTunes gift cards for $40. Sam's Club sells them for $38.88. We are asked to find the percent decrease from Target's price to Sam's Club's price.

We will use percent decrease formula to solve our given problem.

$\text{Decrease percent}=\frac{|\text{Final}-\text{Initial}|}{\text{Initial}}\times 100\%$

$\text{Decrease percent}=\frac{|38.88-40|}{40}\times 100\%$

$\text{Decrease percent}=\frac{|-1.12|}{4}\times 10\%$

$\text{Decrease percent}=\frac{1.12}{4}\times 10\%$

$\text{Decrease percent}=0.28\times 10$

$\text{Decrease percent}=2.8\%$

Therefore, the percent decrease from Target's price to Sam's Club's price is 2.8%.

Fission tracks are trails found in uranium-bearing minerals, left by fragments released during fission events. An article report

Harlamova29_29 [7]

Answer:

Mean track length for this rock specimen is between 10.463 and 13.537

Step-by-step explanation:

99% confidence interval for the mean track length for rock specimen can be calculated using the formula:

M± $\frac{t*s}{\sqrt{N}}$ where

M is the average track length (12 μm) in the report
t is the two tailed t-score in 99% confidence interval (2.977)
s is the standard deviation of track lengths in the report (2 μm)
N is the total number of tracks (15)

putting these numbers in the formula, we get confidence interval in 99% confidence as:

12± $\frac{2.977*2}{\sqrt{15}}$ =12±1.537

Therefore, mean track length for this rock specimen is between 10.463 and 13.537

Find the sum of first 20 to terms of an ap in which d is equal to 7 and 20 second term is 149

GuDViN [60]

Answer:

1370

Step-by-step explanation:

<h3>Given</h3>

AP with d= 7 and a₂₂ = 149

Sum of first 20 terms

<h3>Solution</h3>

<u>First, let's get the value of the first term:</u>

aₙ = a + (n-1)d
a₂₂ = a + 21d
149 = a + 21*7
a = 149 - 147
a= 2

<u>Next, let's find the sum of the first 20 terms</u>

Sₙ = 1/2n(2a+ (n-1)d)
S₂₀ = 1/2*20(2*2 + 19*7) = 10(4 + 133) = 10*137 = 1370

<u>Answer is</u> 1370
