Answer:
17) 288
18) $69.30
19) $56.00
20) $135.00
21) $132.00
22) $4,515
23) 6.9%
Step-by-step explanation:
17)(3 × 4) × (6 × 4) = 288
18) 18% + 8% + 100% = 126%.
$55 × 1.6 = $69.3
19) $32 × 175% = $56
20) 100% - 15% - 10% = 75%
$180 × 0.75 = $135
21) $3,300 × 0.04 = $13
22) 2.5% × 3 = 7.5%
$4,200 × 1.075 = $4,515
23) 58 × 1.069 = 62.002
R=[(-1)(A/1)]-t+P > explanation > P=(A/1)+rt > subtract "r" from both sides to
get > P-r=(A/1)+t > then subtract "P" from both sides to get > -r=(A/1)+t-P >
then multiply the whole equation by "-1" to make "r" positive > (-1){-r=(A/1)+t-P}
> r=[(-1)(A/1)]-t+P .................. if this was not the answer then I'm sorry ... <3
Answer:
<em>John has 11 photos on his phone</em>
Step-by-step explanation:
<u>Equations</u>
Megan has 99 photos on her phone and John has p photos on his phone. It's given Megan has 9 times as many photos on her phone as John has. This leads to the following equation:

Answer:
a) The number of correct answers
b) Discrete
c) Ratio
Step-by-step explanation:
We are given the following in the question:
Experiment:
Evaluate the effectiveness of different study strategies. All students were then given a test on the passage material and the researchers recorded the number of correct answers.
a) The dependent Variable
The number of correct answers given is the dependent variable because it depends on the number of times the passage is read.
b) Nature of dependent variable.
- It is a discrete variable.
- Since, the number of questions will always be expressed in whole numbers and cannot be expressed as decimals.
- They are always counted and not measured.
c) Scale of measurement
- Ratio is used to measure the dependent variable because true zero for the number of correct questions answered exist.
- If the measure is zero that means truly no questions were answered correctly.
