ES is half of EF since a chord is bisected by the radius. ES = 10

If EF is 20 then ES would be half of that because it is half the distance to EF making your answer 10

Find the HCF of 126 and 420

melamori03 [73]

Answer:

Step-by-step explanation:

Find the prime factorization of 126

126 = 2 × 3 × 3 × 7

Find the prime factorization of 420

420 = 2 × 2 × 3 × 5 × 7

To find the GCF, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 3 × 7

GCF = 42

Find the midpoint given the endpoints (4,-10) (22,-4) Please do not use space when

Elza [17]

Answer: (13,-7)

Step-by-step explanation:

By using the formula $(x_{m},y_{m}) =(\frac{x_{1}+x_{2} }{2},\frac{y_{1}+y_{2} }{2} )$

$(x_{m},y_{m})\\$ is the coordinates of the midpoint.

For finding the midpoint X variable do:

$(\frac{4+22}{2})=13$

For finding the midpoint Y variable do:

$\frac{-10+(-4)}{2} = -7$ (you can either keep the parenthesis or take them out. Either way, the answer is the same.

Considering coordinate numbers follow the format: (x,y), you'll simply just substitute the numbers found above into their respective places.

x: 13

y: -7

(13,-7).

PSYCHO15rus [73]

Answer:

c. 61.25 kg

Step-by-step explanation:

The margin of error in estimating the true mean weight of male baluga whales in the Artic Ocean.

a. 15.31 kg

b. 51.40 kg

c. 61.25 kg

d. 80.49 kg

Margin of Error Formula= z × Standard deviation/√n

95% confidence interval = 1.96

Standard deviation = 125kg

n = 16 samples

Margin of error= 1.96 × 125/√16

= 1.96 × 125/4

= 245/4

= 61.25kg

The margin of error in estimating the true mean weight of male baluga whales in the Artic Ocean is 61.25kg
