Answer:

Step-by-step explanation:

6)Let the number  be x

Product of a number and -4  = x * -4 = -4x

Product of a number and -4 increase by 3 : -4x + 3

-4x +3 = 9

Subtract 3 from both sides

-4x + 3 - 3 =  9 - 3

-4x = 6

Divide both sides by (-4)

-4x/-4 = 6/-4

x = -3/2

x = -1 1/2

7)Let the number be x

\frac{x}{6}-9=11\\\\

Add 9 to both sides

\frac{x}{6}-9+9=11+9\\\\\frac{x}{6}=20\\

Multiply  both sides with 6

\frac{x}{6}*6=20*6\\\\

x = 120

Point b has coordinates (3,-4) and lies on the circle whose equation is x^2 + y^2= 25. If angle is drawn in a standard position
lakkis [162]
<span>Point B has coordinates (3,-4) and lies on the circle. Draw the perpendiculars from point B to the x-axis and y-axis. Denote the points of intersection with x-axis A and with y-axis C. Consider the right triangle ABO (O is the origin), by tha conditions data: AB=4 and AO=3, then by Pythagorean theorem:
</span>
<span>BO^2=AO^2+AB^2 \\ BO^2=3^2+4^2  \\ BO^2=9+16  \\ BO^2=25  \\ BO=5.

Researchers investigated the effectiveness of oral zinc, as compared to a placebo, in reducing the found those taking oral durat
MaRussiya [10]

Answer: none of the above

Step-by-step explanation: when performing an hypothesis test and we want to make conclusion by comparing the p-value with the level of significance α

When p is greater than α, we reject the null hypothesis because it simply implies that we have a larger chance to commit a type 1 error ( α is the probability of committing a type 1 error an error where we reject the null hypothesis instead of accepting it ) which means we reject the null hypothesis.

When p is lesser than level of significance α, it means that we have a lesser chance of committing a type 1 error, which means we accept the null hypothesis.
