The probability of a baby being a boy is 0.514.
Nine baby births are selected and we have to find the probability that at last one of them is a girl.
P(At least one out of 9 is baby girl) = 1 - P(No baby girl)
= 1 - P(All 9 are baby boy)
= 1 - (0.514)^9
= 1 - 0.0025
= 0.9975
The probability that at least one out of 9 selected births is baby girl is 0.9975
Answer: 16%
Step-by-step explanation:
The total number of species of shark evaluated = 465
Number of sharks currently endangered or threatened = 74
Percent of sharks endangered = (Number of sharks / Total number of sharks evaluated) x 100%
= (74/465) x 100%
= 0.1591 x 100%
= 15.91%
Round 15.91% to the nearest whole percent = 16%
Thus, 16% of the total sharks evaluated are currently endangered or threatened.
-5.09, -5.25, 1.002
Negative numbers are always the lowest and in decimals .09 is lower then .25
Answer:
3 shirts
Step-by-step explanation:
production cost: c = 28 + 3s
c=cost
3s= 3 shirts
28= dollars she has to add of her own money to be even with the amount she lost making the shirts
money earned= m = 10s
m=money earned from sales
10s= 10 shirts
To turn a number into scientific notation, move the decimal point so that there is only 1 number to the left of the decimal point.
Count the number of spaces you moved the decimal point.
If you move the decimal point to the right, the exponent is negative, if you move it to the left the exponent is positive.
0.000075
You need to move the decimal point 5 places to the right to get 7.5
Because it was moved to the right, the exponent is negative 5
The answer would be 7.5 x 10^-5 which is B.
