11111nata11111 [884]

Answer:

(a) Not confident.

(b) Confident A would win.

(d) Not confident.

Step-by-step explanation:

In order for us t be confident that Candidate A will win, Candidate A's percentage minus the margin of error must be higher than Candidate B's plus the margin of error.

(a)

$A = 54\%-5\%=49\%\\B = 46\%+5\%=51\%$

Not confident.

(b)

$A = 52\%-1\%=51\%\\B = 48\%+1\%=49\%$

Confident A would win.

(c)

$A = 53\%-3\%=51\%\\B = 47\%+2\%=49\%$

Confident A would win.

(d)

$A = 58\%-10\%=48\%\\B = 42\%+10\%=52\%$

Answer:

37.699 cm³

Step-by-step explanation:

Sa of cone:

pi×r×l + pi×r²

(3pi × l) + (pi × 3²) = 24pi

3l + 9 = 24

3l = 15

l = 5 (slant height)

Height: h

h² + r² = l²

h² + 3² = 5²

h² = 16

h = 4 cm

Volume = ⅓ × pi × r² × h

= ⅓ × pi × 3² × 4

= 12pi cm³

= 37.69911184 cm³
