Right triangle EFG and right triangle EHG overlap as shown below. Angle HEG measures 35° and angle FGE measures 30°.
lesantik [10]

Given:

Triangle EFG and EHG are two right triangles.

m\angle HEG=35^\circ

m\angle FGE=30^\circ

To find:

The values of x and y.

Solution:

In triangle EFG,

m\angle EFG+m\angle FGE+m\angle FEG=180^\circ        [Angle sum property]

90^\circ+30^\circ+(x+35)^\circ=180^\circ

(x+155)^\circ=180^\circ

x+155=180

x=180-155

x=25

In triangle EHG,

m\angle EHG+m\angle HEG+m\angle EGH=180^\circ        [Angle sum property]

90^\circ+35^\circ+(y+30)^\circ=180^\circ

(y+155)^\circ=180^\circ

y+155=180

y=180-155

y=25

Therefore, the value of x is 25 and the value of y is also 25.

In a destructive test of product quality, a briefcase manufacturer places each of a simple random sample of the day’s production
Pepsi [2]

Answer:

The lower confidence limit of 99% confidence interval for the mean breaking strength of the briefcases produced today would be equal to 331.09 pounds.

Step-by-step explanation:

Lower limit of confidence interval = mean - Error margin (E)

mean = 341.0 pounds

sd = 21.5 pounds

n = 35

degree of freedom = n - 1 = 35 - 1 = 34

confidence level = 99%

t-value corresponding to 34 degrees of freedom and 99% confidence level is 2.728

E = t × sd/√n = 2.728 × 21.5/√35 = 9.91 pounds

Lower limit = 341.0 - 9.91 = 331.09 pounds

New packaging for fruit snacks contains 10% less weight than the original packaging. If the new package costs 15% more than the
xz_007 [3.2K]

Answer:

5/18

Step-by-step explanation:

Let's say the original packaging was 1 lb of packaging for $1.

The cost was $1/lb.

Then the weight went down by 10% and the price went up by 15%.

Now 0.9 lb of packaging cost $1.15.

The new unit cost is $1.15/(0.9 lb)

The difference is

$1.15/(0.9 lb) - $1/lb =

= $1.15/(0.9 lb) - $0.9/(0.9 lb)

= $0.25/(0.9 lb)

=$25/(90 lb) = $5/(18 lb)

The price went up by 5/18.
