that's what I got
Answer:
5.13
Step-by-step explanation:
Number of sampled workers= n= 1000
Percentage of residents favouring construction= p' = 60% = 60/100= 0.6.
Testing the claim that the percentage of people favouring the construction is more than 56%= p= 56/100 = 0.56.
To calculate the test statistics we use the formula below;
Test statistics= √n (p' - p)/ √[p×(1-p)] -----------(1).
Substituting the value into equation (1) above, we have;
Test statistics= √1000 (0.6-0.56) / √[0.56×(1-0.56)]
Test statistics= (31.62)(0.04) / √0.5(0.44) = 1.2648/ 0.2464
Test statistics= 5.13312
= 5.13 (to 2 decimal places)
Answer:
$3.97
Step-by-step explanation:
Three containers @$2.98 = 3 × 2.98 = $8.94
Less $1 = <u>-1.00
</u>
7.94
Less 50% paid my mom = ½ × 7.94 = <u>-3.97
</u>
Paid by Theresa = $3.97
[(3 × 2.98) - 1] ÷ 2 = (8.94 - 1) ÷ 2 = 7.94 ÷ 2 = 3.97
The solutions to the given inequalities are x < 6 OR x < -10
<h3>Linear Inequalities </h3>
From the question, we are to solve the given inequalities
The given inequalities are
6x - 4(2x - 5) > 8 or 5x + 9 < 2x - 21
First solve,
6x - 4(2x - 5) > 8
Clear the bracket
6x -8x + 20 > 8
6x - 8x > 8 - 20
-2x > -12
Divide both sides by -2 and flip the sign,
That is,
-2x/-2 > -12/-2
x < 6
For,
5x + 9 < 2x - 21
Subtract 2x from both sides
5x - 2x + 9 < 2x - 2x -21
3x < -21 -9
3x < -30
Divide both sides by 3
3x/3 < -30/3
x < -10
Hence, the solutions to the given inequalities are x < 6 OR x < -10
