Answer:
290
Step-by-step explanation:
f(x) = 
f(10) = 
= 3 * 100 - 10
= 300 - 10
= 290
I got y=2/5x+31/5 as the answer
Answer:
1. AB is a diameter. (False)
2. ST, SP and SQ are radii. (True)
3. SQ = 12 cm. (False)
4. PQ is 12 cm. (True)
Step-by-step explanation:
1. AB is not a diameter because a diameter must pass through the center of the circle.
2. ST, SP and SQ are radii because they all meet at the center of the circle.
3. SQ is not equal to 12 cm. SQ is equal to 6 cm because it is a radius.
4. PQ is equal to 12 cm because it is a diameter. Radius = 6 cm. Diameter = 2 × radius = 2 × 6 cm = 12 cm
Answer:
110cm square
Step-by-step explanation:
Area of trapezium(regardless whatever trapezium)=
1/2 (a+b)(height)=1/2 (9+13)(10)=110cm square
Answer:
Null hypothesis (
): The birth weight of the first born of identical twins is the same as the birth weight of the second born.
Alternative hypothesis (
): The birth weight of the first born of identical twins is higher than the second born.
Step-by-step explanation:
Please note that the null hypothesis is the hypothesis we always want to reject or prove to be false. Hence in this study, the objective of the study is clearly stated that the researcher want to determine whether the twin born first tends to weigh more than the twin born second.
Therefore, the null hypothesis we assume that the weight of the identical twins is the same regardless of who come first or last., while the alternative hypothesis is constructed or stated to answer the research objective.
