A circle shown below, m AC = 89° and m BC = 153°. Determine m∠ACB.

Mathematics
1 answer:
Phoenix [80]2 years ago
4 0

Answer:

m<ACB  = 59degrees

Step-by-step explanation:

To get <ACB, first we need arcAB

arcAB + arcAC + arcBC = 360

arcAB + 89 + 153 = 360

arcAB+242 = 360

arcAB = 360 - 242

arcAB = 118

Also, m<ACB = 1/2arcAB

m<ACB = 1/2*118

m<ACB  = 59degrees

An experiment was conducted as a one-way factorial design with K sample means, each based on n scores. What is the number of deg
nordsb [41]

Answer:

The mean squares has d.f (n-1)

Step-by-step explanation:

The total number of degrees of freedom is n-1 as there is only one restriction of computing the grand mean. The d.f for k samples is k-1 beacuase the mean of the sample means must equal the grand mean. Similarly , the d.f for within SS is n-k , due to the k restrictions of computing the k sample means. Hence we find that

Total df= Within df + Between df

n-1=  (n-k)+(k-1)

Between SS has (k-1) d.f

Within SS has (n-k) d.f

These two quantities are known as mean squares and has d.f (n-1)

This is a division problem.
You need to divide 51/2 by 3/2.

\dfrac{51}{2} \div  \dfrac{3}{2} =

= \dfrac{51}{2} \times  \dfrac{2}{3}

= \dfrac{51 \times 2}{2 \times 3}

= \dfrac{102}{6}

= 102 \div 6

= 17

find two consecutive intergers who sum is equal to the difference of three times the larger and two times the smaller
vekshin1

Answer:

4 and 6

Step-by-step explanation:

Let integers be x and x+2 Then:-

x + x + 2  = 3(x + 2) - 2x

2x + 2 = 3x + 6 - 2x

2x + 2 = x + 6

x = 4

The numbers are 4 and 6.

State whether the ratios form a proportion.
Liula [17]
16 to 18 simplifies down to 8 to 9 because you divide 2 to both terms
24 to 27 simplifies down to 8 to 9 because you divide 3 to both terms
So yes
