Mathematics
1 answer:
Sedbober [7]3 years ago

Answers and Explanation:

So I'm not sure about this at all since you probably already know:    

For number 9, the rule would be that it "Multiplies by -3" or however you would write that (I haven't done this in a while.)  This is because 7×-3=-21, -21×-3 is 63, and so on.  

For number 10, the rule would be "It Multiplies by 3" for the same reason.  

Sorry that this probably wasn't helpful because I don't know too much about the terms.

Answer:

(below)

c) the angles are in the interior on the same side of the transversal, making them supplementary

equation: 2x + 20 + 120=180 and then when solved you would get x =20

d) the angles are corresponding, which makes them congruent

equation: 3x + 10 = 100 and then when solved you would get x = 30

weeeeeb [17]

Answer:

(a)0.3303

(b)0.6697

Step-by-step explanation:

Point estimation is the use of sample data to calculate a single value which serves as a best estimate of a given unknown population parameter.

Total Sample=1226

Number who said that they were not confident that the food they eat in country A is safe=405.

The point estimate of those who said that they were not confident that the food they eat in country A is safe is given as \^{p}

(a)Point Estimate for p,

\^{p}=\frac{405}{1226} =0.3303

(b)Point estimate for q, \^{q}=1- (point estimate for p)

=1-0.3303

=0.6697

80% of a gram.
One gram is $100, aka $100 is 100% of a gram, so $80 would be 80% of a gram.
