null hypothesis: H0 = 5.5
alternative hypothesis: Ha different 5.5
standard error = 1 / (31) 1/2= 0.1796
we deduce that:
t stat = (5.2-5.5) /0.1796 = -1.67033
p-value = 0.105
the null hypothesis cannot be rejected because the value of p is greater
Answer:
29
Step-by-step explanation:
The Trapezoid Midsegment segment theorem states that the length of the midsegment is half the sum of the length of its two parallel sides. Therefore:
MN = ½(AB + DC)
MN = ½(21 + 37)
MN = ½(58)
MN = 29
Answer:
±1, ±2, and ±4
Step-by-step explanation:
4x² + bx + c = (Ax + B) (Cx + D)
Distribute:
4x² + bx + c = ACx² + (AD + BC) x + BD
Matching the coefficients, AC = 4. So A must be a factor of 4. Possible values of A are therefore ±1, ±2, and ±4.

Negative. You have $252, and the check will take away $287, so 252-287 is -35.
