The family leave home at 9 A.M. At that point, the car's odometer reads 31,247. They drive until 12:30 P.M., when they stop for

Answer:

$\text{Speed} = 70 \text{ miles per hour}$

Step-by-step explanation:

The car shift is $31,492-31,247 = 245 \text{ miles}$

Time passed: $3.5 \text{ h}$

Once Speed is $\frac{\text{Distance}}{\text{Time}}$

$\text{Speed} =\frac{\text{245}}{\text{3.5}}$

$\text{Speed} = 70 \text{ miles per hour}$

Suppose that 16-ounce bags of chocolate chip cookies are produced with weights that follow a normal distribution with mean weigh

AysviL [449]

To solve this we use the z statistic. The formula for z score is:

z = (x – u) / s

where x is the sample value = less than 16, u is the sample mean = 16.1, s is standard dev = 0.1

z = (16 – 16.1) / 0.1

z = - 1

From the standard distribution tables at z = - 1,

P (z = -1) = 0.1587

So about 15.87% is underweight.

Option 2: Find m < C. Show all work.

maksim [4K]

Answer:

m∠C = 28.1°

Explanation:

angle m∠C has opposite angle of 16 and hypotenuse of 34

using sine rule:

$\boxed{ sin(C) = \frac{opposite}{hypotenuse}}$

$sin(C)=\frac{16}{34}$

$C = sin^{-1}(\frac{16}{34} )$

C = 28.07248°

C = 28.1°

5/8 + 1 1/4 = x/10 solve for x

lara [203]

Answer:

x = 75/4

Step-by-step explanation:

5/8 + 1 1/4 = x/10

5/8 + 5/4 = x/10

15/8 = x/10

8x = 15 × 10

8x/8 = 150/8

x = 150/8

x = 75/4
