Los hombres adultos tienen alturas con una media de 69.0 pulgadas y una desviación estándar de 2.8 pulgadas. Encuentre la puntuación z de un hombre de 70.3 pulgadas de alto. (Redondee la respuesta con 4 decimales)
Answer:
0.4643
Step-by-step explanation:
z = (x-μ) / σ, donde
x es la puntuación bruta = 70.3 pulgadas
μ es la media de la población = 69 pulgadas
σ es la desviación estándar de la población = 2.8 pulgadas
z = (70.3 - 69) /2.8
z = 0.46429
Aproximadamente a 4 lugares decimales = 0.4643

A population of 2500 frogs increases exponentially at an annual rate of 25%. Which equation below best represents the population (P) in t years?
P=2500(0.25)^t
P=2500+0.25t
P=2500(0.75)^t
P=2500(1+0.25)^t
Answer:
P=2500(1+0.25)
Step-by-step explanation:
Given data
Initial population= 2500
Rate= 25%
The exponential increase is described using the expression
P=A(1+r)^t
Hence the correct representation is
P=2500(1+0.25)

One game had an attendance of 25,000 visitors. Based on the table, how many people out of 25,000 could be expected to buy a flag?
A.
1,375
B.
1,650
C.
3,850
D.
2,750
The number of people who could be expected to buy a flag using the expression (22/200) x 25,000 is 2,750.
Option D is the correct answer.
We have,
Based on the table,
The number of people who could be expected to buy a flag out of 25,000 visitors is:
(22/total items sold) x 25,000
To find the total items sold, you can add up the number of caps, jerseys, flags, and programs:
Total items sold.
= 68 + 19 + 22 + 91
= 200
The number of people who could be expected to buy a flag is:
(22/200) x 25,000 = 2,750
Thus,
The number of people who could be expected to buy a flag is 2,750.

total puzzle heather put together =
[tex]\frac{2}{5} + \frac{3}{10}[/tex]
[tex]\frac{4 + 3}{10}[/tex] = 7/10
the next step is to subtract 7/10 from the fraction Nicole put together
[tex]\frac{4}{5} - \frac{7}{10}[/tex]
[tex]\frac{8-7}{10}[/tex] = 1/10
