Answer:
56 chairs
Step-by-step explanation:
856+700=1556 <--- expected count
chairs set up= 1500
1556-1500= 56 more chairs
Answer:
for #9:
tan 30=x/10
tan 30*10=x
x=5.77=5.8
for #10:
tan 40=4/x
x*tan 40=4
x=4/tan 40
x=4.76=4.8
Step-by-step explanation:
hope all that helped lol
Answer: the monthly payment is $1530.1
Step-by-step explanation:
The cost of the house is $319,000.
The down payment made is 20%. This means that the amount paid as down payment is
20/100 × 319000 = 63800
The balance to be paid would be
319000 - 63800 = $255200
We would apply the periodic interest rate formula which is expressed as
P = a/{[(1+r)^n]-1}/[r(1+r)^n]
Where
P represents the monthly payments.
a represents the amount of the loan
r represents the annual rate.
n represents number of monthly payments. Therefore
a = $255200
r = 0.06/12 = 0.005
n = 12 × 30 = 360
Therefore,
P = 255200/{6.0226 -1}/[0.005(6.0226)]
P = 255200/166.79
P = 1530.1
Answer:
6+5/18
Step-by-step explanation:
the probability that both are blue;
4/9 × 3/8 = 6
the probability that only one is blue;
4/9 × 5/8 = 5/18
6 + 5/18
Answer:
Number of independent variables = 2
Step-by-step explanation:
Lets stary with definitions. First of all, variables are properties, of an experiment that take on different amounts or values, rather than a constant that has one unchanging value assigned to it.
Now, we have two kinds of variables namely dependent and independent variables. For this question, we need to know independent variables. Independent variables are variables that could be manipulated at discretion. In the question, the independent variable is "the size of breakfast" because the experimenter chose by reason of choice to either use 350-calories or 750- calories breakfast.
However, the dependent variables are those whose outcomes are with respect to the change in the independent variable. The experiment is actually out to observe how the dependent variable plays out during the experiment. In our example, the dependent variable is "overall food consumption throughout the rest of the day". Thus, the outcome of the overall food consumption throughout the rest of the day is as a result of the size of breakfast taken.
Now, the independent variable can take on various levels, and the number of levels are the number of experimental conditions that the independent variables can take. In our example the independent variable (size of breakfast), was either 350-calories breakfast or 750-calories breakfast, hence it took 2 experimental conditions.
Thus, we say that number of independent variables is 2.
