Answer:
y=3x
Step-by-step explanation:
The equation of the line is y=3x
Answer:
D. Omar's transaction involves more money, because |-15| is greater than |10|.
Step-by-step explanation:
The absolute value of a number is simply the magnitude or numerical value of a number while ignoring any sign attached to it. For example, given that x is a real number, absolute value of x, |x| = x. The absolute value of x does not take account of any sign attached to it.
Thus:
The absolute value of Omar's transaction is given as |-15| = 15.
While that of Jake is |10| = 10.
15 is greater than 10.
Therefore, we can conclude that:
"Omar's transaction involves more money, because |-15| is greater than |10|."
Answer:
there is significant evidence to support that the claim that the mean time women spend watching television less than the mean time spent by men.
Step-by-step explanation:
H0 : μw = μm
H1: μw < μm
The test statistic :
(x1 - x2) / sqrt[(sp²/n1 + sp²/n2)]
df1 = 14 - 1 = 13
df2 = 17 - 1 = 16
Pooled variance = Sp² = (df1*s1² + df2*s2²) ÷ (n1 + n2 - 2)
Sp² = ((13*4^2) + (16*4.2^2)) ÷ (13 + 16)
Sp² = 16.90
t = (12.9 - 16.4) ÷ sqrt((16.90/14 + 16.90/17))
t = - 3.5 ÷ 1.4836645
t = - 2.359
Using the Pvalue from Tscore ; at 95% ; df = 29
Pvalue = 0.0126
Pvalue < α
0.0126 < 0.05 ;
Hence, we reject the null and conclude that there is significant evidence to support that the claim that the mean time women spend watching television less than the mean time spent by men.
Answer:
y=8
Step-by-step explanation:
4−2y+3=−9
Step 1: Simplify both sides of the equation.
4−2y+3=−9
4+−2y+3=−9
(−2y)+(4+3)=−9(Combine Like Terms)
−2y+7=−9
−2y+7=−9
Step 2: Subtract 7 from both sides.
−2y+7−7=−9−7
−2y=−16
Step 3: Divide both sides by -2.
−2y
−2
=
−16
−2
y=8
4 to 7
or
4+7= 12
4x+7x=33
x=3
so,
(4×3)+(7×3)=33
12+21=33
or
12 and 21.
hope it helped
