A cone-shaped dispenser is filled with cereal. The cone has a radius of 1.5 inches and a height of 5 inches. Which measurement i

Svetach [21]

Answer:

Option B. $11.78\ in^{3}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3} \pi r^{2}h$

we have

$r=1.5\ in$

$h=5\ in$

substitute

$V=\frac{1}{3} \pi (1.5)^{2}(5)$

$V=3.75\pi\ in^{3}$

assume

$\pi =3.14$

$V=3.75(3.14)=11.78\ in^{3}$

1. Average Senior High School annual cost of tuition fee for all private schools in Cavite last year was 46,300 a random sample

anygoal [31]

Answer:

Step-by-step explanation:

H0 : μ = 46300

H1 : μ > 46300

α = 0.05

df = n - 1 = 45 - 1 = 44

Critical value for a one tailed t-test(since population standard deviation is not given).

Tcritical = 1.30

The test statistic :(xbar - μ) ÷ (s/sqrt(n))

The test statistic, t= (47800-46300) ÷ (5600√45)

t = 1500

t = 1500 / 834.79871

t = 1.797

The decision region :

Reject H0: if t value > critical value

1. 797 > 1.30

Tvalue > critical value ; We reject H0

Hence, there is sufficient evidence to conclude that cost has increased.

The length of each square on the grid represents 1 cm. The scale

tatyana61 [14]

Answer:

Step-by-step explanation:

Length of the rectangle given in the the figure attached = 2 cm

Width of the rectangle = 5 cm

Scale used, 24 in to 1 cm

Therefore, length of actual rectangle = 2×24 = 48 in

width of the actual rectangle = 5×24 = 120 in

Now we have to draw a drawing by using the scale,

16 inches to 1 cm

Or 1 inch = $\frac{1}{16}$ cm

Therefore, length of the rectangle drawing = $48\times \frac{1}{16}$

= 3 cm

Similarly, width of the rectangle drawing = $120\times \frac{1}{16}$

= 7.5 cm
