Type the integer that makes the following addition sentence true: -3 + = -11

2 answers:

It'd be clearer if you'd type -3 + ( ) = -11. Adding 3 to both sides,

( ) = -11 + 3 = -8

Check: Is -3 - 8 = -11? YES

An integer that would work is 14 so -3 + 14 = -11

Answer:

The observed value of the chi-square statistic is 34.71

Step-by-step explanation:

Given the data in the question';

Calculate the observed value of the chi-square statistic

The chi-square statistic will be;

∑ $_{i}$ [ ( O $_{i}$ - E $_{i}$ )² / E $_{i}$ ]

here O $_{i}$ is observed frequency of $_{i}$ th class

E $_{i}$ is expected frequency of $_{i}$ th class

$_{i}$ = 1, 2 which denote the class of food experts who guess correctly and who didn't guess correctly

∈ $_{i}$ = n × probability of not guessing correctly = 168 × 2/3 = 112

∈1 = n × probability of guessing correctly 168 × 1/3 = 56

∑ $_{i}$ [ ( O $_{i}$ - E $_{i}$ )² / E $_{i}$ ] = [ ( 92 - 56)² / 56 ] + [ ( 76 - 112)² / 112 ]

= 1296/56 + 1296/112

= 23.14 + 11.57

= 34.71

Therefore, the observed value of the chi-square statistic is 34.71

A taxi company change $2.25 for the first 5 miles and $0.75 for each mile. If a passenger spent $6 on a trip, how many miles did

Monica [59]

Answer:

10 miles

Step-by-step explanation:

Setting up an equation where the variable 'x' = the number of miles, we can find the total mileage for the passenger's trip:

$6 = $0.75x + $2.25

$6 = the total amount of the trip

$0.75 = the cost for each mile after the initial 5 miles

$2.25 = the flat fee for the first 5 miles

Solve for 'x', subtract $2.25 from both sides: 6 - 2.25 = 0.75x + 2.25 - 2.25 or 3.75 = 0.75x

Divide by 0.75: 3.75/0.75 = 0.75x/0.75 or x = 5 miles

Since the passenger was charged in additional 5 miles, then the total mileage is 10 miles.
