Gina bought 5 hot dogs and 3 drinks for 11.50. Renaldo bought 4 hot dogs and 2 drinks for 8.50.How much does each hot dog and dr
stiks02 [169]
5h + 3d  = 11.50   * 2
4h + 2d = 8.50      * 3

10h + 6d =  23
 12h + 6d = 25.50

subtract  the former equation from the latter:-

2h = 2.50
h = 1.25

so susbstituting in the second equation

4(1.25) + 2d = 8.50 
 5 + 2d = 8.50
2d =  3.50
d = 1.75

hot dogs cost  $1.25 and drinks cost $1.75

Romashka-Z-Leto [24]
The trigonometric ratios are used for right angle triangle.The basic rule to followed is SOH CAH TOA

SOH means Sinx=opposite/Hyp.
CAH means Cosx = adj./Hyp.
TOA means Tanx = Opp./Adj.

Opposite is the side opposite to the acute angle of the right triangle.

<span>Adjacent is the side Adjacent to the acute angle of the right triangle.

The times of the runners in a marathon are normally distributed, with a mean of 3 hours and 50 minutes and a standard deviation
balu736 [363]

Answer: 0.16

Step-by-step explanation:

Given that the run times provided are normally distributed ;

Mean(x) of distribution = 3 hours 50 minutes

Standard deviation(s) = 30 minutes

The probability that a randomly selected runner has a time less than or equal to 3 hours 20 minutes

3 hours 20 minutes = (3 hrs 50 mins - 30 mins):

This is equivalent to :

[mean(x) - 1 standard deviation]

z 1 standard deviation within the mean = 0.84

z, 1 standard deviation outside the mean equals:

P(1 - z value , 1standard deviation within the mean)

1 - 0.8413 = 0.1587

= 0.16
