Kruka [31]

Answer:

0.6848

Step-by-step explanation:

Mean of \hat{p} = 0.453

Answer = 0.453

Standard deviation of \hat{p} :

= \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} = \sqrt{\frac{0.453(1-0.453)}{100}} = 0.0498

Answer = 0.0498

P(0.0453 - 0.05 < p < 0.0453 + 0.05)

On standardising,

= P(\frac{0.0453-0.05-0.0453}{0.0498} <Z<\frac{0.0453+0.05-0.0453}{0.0498})

= P(-1.0044 < Z < 1.0044) = 0.6848

Answer = 0.6848

Larry gets $7 for each of the 3 flower beds he weeds and Y dollars to edge a yard. Zach will get $25 to clean a garage and Y dol
lbvjy [14]

Answer:

Expression for Larry will be;

\$21 + \$Y\geq \$X

Expression for Zach will be;

\$25 + \$Y\geq \$X

Step-by-step explanation:

Given:

Larry gets $7 for each of the 3 flower beds he weeds and Y dollars to edge a yard.

Amount for each flower bed he weeds = $7

Number of flower bed he weeds = 3

Total amount he gets for 3 flower bed he weeds = \$7\times 3 =\$21

Amount earn to edge a yard = Y

Total amount Larry will earn = $21 + $Y

Now Zach will get $25 to clean a garage and Y dollars to wash a car.

Amount earned to clean garage = $25

Amount earned to wash as car = $Y

Total Amount Zach will earn = $25 + $Y

The Both have to make X dollars to meet their goals.

Expression for Larry will be;

\$21 + \$Y\geq \$X

Expression for Zach will be;

\$25 + \$Y\geq \$X

State the Rules for Reflection across the x-axis and across the y-axis
prisoha [69]

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).
