57.7r + 23.23 =2.57

Subtract 23.23 from both sides:

57.7r = -20.66

Divide both sides by 57.7

r = -20.66 / 57.7

r = -0.358

round to nearest tenth = 0.4

Arturiano [62]

Answer:

Test statistic = -2.44

There is enough evidence to support the strategist's claim.

Step-by-step explanation:

H0 : p = 0.41

H1 : p < 0.41

pˆ = 0.38

Test statistic :

z=pˆ−p/√p(1−p)/n

Z = (0.38 - 0.41) / √(0.41(1 - 0.41) / 1600

Z = - 0.03 / √0.0001511875

Z = - 0.03 / 0.0122958

Z = - 2.4399

Test statistic = -2.44

The Pvalue :

P(Z < -2.44) = 0.0073436

α - level = 0.02

If Pvalue < α ; Reject H0

0.0073436 < 0.02 ; We reject H0

Since Pvalue < α ; Hence, There is enough evidence to support the strategist's claim.

isabella is covering a square tabletop with square mossaic tiles.the tabletop is 2ft. long and 2ft.wide.each tile is 1/4 in.long
Hunter-Best [27]
Convert the feet to inches first.  2 ft = 24 inches.  We must divide this total length by the length of each tile to determine how many tiles will fit across the tabletop:

24 ÷ (1/4) = (24/1) ÷ (1/4) = (24/1) × (4/1) = 96/1 = 96

96 tiles will fit across the tabletop.
Since the tabletop is as long as it is wide, that means we will have 96 rows of 96 tiles:
96(96) = 9,216 tiles to cover the tabletop.
