Answer:
891
Step-by-step explanation:
The number/38=23+17/38
The number=891
8k = 4/9
Divide 8 to both sides, or multiply by its reciprocal 1/8:
k = 4/9 * 1/8
k = 4/72
k = 1/18
Answer:
x=30
Step-by-step explanation:
90-70= 20 so y=20
20+40=60 and 90-60=30
so x=30

Lateral area: AL = 4 * s * h
624 = 4 * s * 13
624 = 52 s
s = 624 : 52
s = 12 cm
The surface area of the prism:
A = 2 ·12² + 624
A = 2 · 144 + 624 = 288 + 624 =912 cm²
The volume:
V = a² · h = 12² · 13 = 144 · 13 = 1,872 cm³
Answer:
1. The surface area is equal to 912 cm².
2. The volume is equal to 1,872 cm³.
Answer:
99.7%
Step-by-step explanation:
According to the Empirical Rule:
- 68% of data in a normal distribution are ±1σ from the mean μ
- 95% of data in a normal distribution are ±2σ from the mean μ
- 99.7% of data in a normal distribution are ±3σ from the mean μ
By calculating the z-score of each observed value, we can determine how many standard deviations these observed values are from the mean:


Clearly, we can see that 99.7% of males in the town have a systolic blood pressure between 99 and 141 by the Empirical Rule.
