Credit score and if they pay on time
Answer:
x=12
Step-by-step explanation:
Since the angle needs to add up to 90, you will first need to subtract 30 from 90. This will leave you with 60. Next you will divide 60 by 5 which will give you 12 which is the answer.

Answer:
C) $20.80
Step-by-step explanation:
1 kg of cooking oil = $6.5
1 packet of cooking oil =2/5 kg
If 1 kg of cooking oil = $6.5
2/5kg of cooking oil = $X
Cross Multiply
1kg × $X = 2/5kg × $6.5
$X = 13/5
$X = 2.6
Hence 2/5kg of oil cost $2.6
Since 1 packet of oil = 2/5kg of oil , 1 packet of oil cost $2.6
The amount she spent if she bought if she bought 8 packets of the cooking oil is calculated as:
1 packet of oil = $2.6
8 packets of oil =
$2.5 × 8
= $20.80
Therefore,if Sara bought 8 packets of oil, the amount she would spend = $20.80
Answer:
0.6563 or 65.63% of brook trout caught will be between 12 and 18 inches
Step-by-step explanation:
Mean trout length (μ) = 14 inches
Standard deviation (σ) = 3 inches
The z-score for any given trout length 'X' is defined as:
e interval
For a length of X =12 inches:
![z=\frac{12-14}{3}\\z=-0.6667](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B12-14%7D%7B3%7D%5C%5Cz%3D-0.6667)
According to a z-score table, a score of -0.6667 is equivalent to the 25.25th percentile of the distribution.
For a length of X =18 inches:
![z=\frac{18-14}{3}\\z=1.333](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B18-14%7D%7B3%7D%5C%5Cz%3D1.333)
According to a z-score table, a score of 1.333 is equivalent to the 90.88th percentile of the distribution.
The proportion of trout caught between 12 and 18 inches, assuming a normal distribution, is the interval between the equivalent percentile of each length:
![P(12\leq X\leq 18) = 90.88\% - 25.25\%\\P(12\leq X\leq 18) = 65.63\%](https://tex.z-dn.net/?f=P%2812%5Cleq%20X%5Cleq%2018%29%20%3D%2090.88%5C%25%20-%2025.25%5C%25%5C%5CP%2812%5Cleq%20X%5Cleq%2018%29%20%3D%2065.63%5C%25)
