Answer:

1.8-9=8+(-9)=?

2.+5-(14)= -9

3. -10-(-9)= -1

6.16-(+16)= 0

5.(+17)-(-20)-(12)= 25

8.5-(+7)-(-8)-3-(6)=9

7.-200-(-120)-25=105

10.-18+(-22)-(-31)=9

9.53-(-17)+(-6)=64

that's my answer

Translate the statements into a confidence interval for p. Approximate the level of confidence. In a survey of 8451 U.S. adults,

Sedaia [141]

Answer:

The confidence interval is $0.304 < p < 0.324$

Step-by-step explanation:

From the question we are told

The sample proportion $\r p = 0.314$

The margin of error is $E = 0.01$

The confidence interval for p is mathematically represented as

$\r p - E < p < \r p + E$

=> $0.314 - 0.01 < p < 0.314 + 0.01$

=> $0.304 < p < 0.324$

What is the value of the expression? Enter the answer in the box.<br> 4+(8 - 7) X6-1

e-lub [12.9K]

Answer: 9

Explanation: you would use PEMDAS to solve the algebraic expression first by doing parentheses so subtract 8 and 7 which leaves you with 4 + 1 times 6-1. You would then multiply 1 into 6 which would leave you with 4 + 6 - 1 which you would then sum up 4 and 6 which leaves you with 10-1 which would give you the answer of 9

So the answer would be 9

Hope this helps!

A projectile is shot into the air following the path,h(x) = - 5t2 + 20t + 3. At what time will it reach a maximum height? t = 1

kramer

Answer:

t = 2

Step-by-step explanation:

Notice that this expression for the projectile's path is that of a quadratic function with negative leading term. The graph of it therefore consists of a parabola with the branches pointing down (due to he negative leading coefficient). Therefore, the maximum of such parabola will reside at its vertex.

Recall that the formula for the position of the vertex in a general parabolic function of the form: $y(x)=ax^2+bx+c$ , is given by the expression: $x_{vertex}=-\frac{b}{2a}$

In our case, the variable "x" is in fact "t", the leading coefficient ( $a$ ) is -5, and the coefficient for the linear term ( $b$ ) is 20.

Therefore, the maximum of the path will be when $t=-\frac{20}{2(-5)} =\frac{20}{10} =2$
